Learn the different types of Human Body Parts names with an image in American English. An image-based list of all human body parts. The human body is an integral part of the human person. It is made up of different types of cells, which together make tissue. A group of tissues makes an organ. Certain organs combine functions to create a system that enables a human body to perform its functions.
According to the references of different systems, the list of human body parts can vary. Anatomy science refers to the study of the parts of the body and living organisms.
There are around 79 organs within a human body. Because all five are vital parts of survival, any damage to these organs can lead to the end of life. These organs are the brain, liver, kidneys, lungs and heart.
Human structure can also be described by the essential part. It is covered with hairs, has mammary glands, and sense organs. There are many body cavities, and separate areas that are placed in different organ systems. Individually, sex and the age of a person can affect how they change their body’s external appearances, such as height, weight, or other proportions.
The top portion of the human body, the head, is considered the most important part. Other parts include the ears, nose and eyes, cheeks, brain, mouth, tongue and brain. Each of these sensory functional parts is part of the head. It is a bilaterally symmetrical part of the body that doesn’t matter how large it may be.
The forehead is an area of the head that’s surrounded by three characteristics: two of the skull, one of scalp. Hairs surround the forehead’s top. The supraorbital Ridge, which is the bone feature in the skull that is above the eyes, marks the bottom.
The hair follicle is the part of hair that attaches to the skin. The base of the hair bulb is the hair follicle. It is fed by the blood vessels in the body. Hair growth is dependent on hormones and the growth of life.
The ear, a hearing organ in the body, has three parts. The outer ear includes the pinna, the ear canal and the middle ear contains the tympanic cavities and three ossicles. While the inner ear houses the bony labyrinth. The ears of vertebrates are located on the opposite side of the head.
The human eye is an organ which reacts to light and visions that are permitted by cells. The retina, pupil, as well as other cells, are all part of the eye. These cells help us to see an image when we look at things. One photon can be detected by the human eye, which can differentiate between 10 million colours.
The nose is the main organ of the human body and it is located in front of the eyes. The first organ of the respiratory system is the nostrils. The nose is an important organ of the olfactory systems.
The cartilages determine the shape and size of the nose, which includes the septum. This septum is separated from the nostrils by the nasal cavity.
The cheeks are located below the eyes, between the nose and the right and left ear. This is the buccal nerve, which is located between the cheeks and the gums and teeth is also known as the vestibule.
The neck is an area of the body that lies below the head. It allows the head to move. The human neck is anatomically divided into four parts: vertebral, visceral and two vascular. The ducts or glands that run from the head to abdominal part of the body via the thorax were found within these compartments.
The first part of the alimentary canal that connects to the oesophagus is the human mouth. It is located just above and below the nose. The lips are the coverings of the mouth.
The human chin is the forward-pointing part of the anterior mandible, 2below your lower lip. Due to the multi-layered skins of the face, obese people might appear to have double chins.
The three bones that make up the human shoulder are the cervical, scapula and humerus. These bones are also surrounded by ligaments and tendon muscles. The major joint of the shoulder is known as the glenohumeral or shoulder joint.
The thorax, another name for the chest is also part of the anatomy human and other animals. The thorax lies between the neck and abdomen. It contains the thalamus gland and the thoracic cavity, as well as various muscles and other internal structures.
To divide the abdomen into quadrants, the umbilicus is used. The umbilicus is prominently visible on the abdomen and is fairly constant between humans.
The upper limbs of humans are the arms. They are located between the elbow joint and the glenohumeral. The arms can be divided into two parts. The upper arm extends from your shoulder to your elbow and the lower arm, also known as the forearm, extends from your elbow to the hand. This is symmetrical to the shoulder joints and the body.
The human back (also known as the dorsum) is the largest posterior part of the human body, extending from the top of your buttocks to the back end of the neck. The surface portion directly opposite the chest. The shoulders at the top and pelvis at bottom create the breadth of your back. The central air of recession is created by the vertebral column passing through the back.
The elbow is the visible joint between the upper forearm and lower arm. It is distinguished by the elbow pit, epicondyles and elbow joint. The elbow joint, a synovial hinge between the humerus, the radius and ulna of the forearm is a joint that allows the lower arm to move in 180 degrees.
The abdominal area is located between the pelvis and thorax in the human body. It can also be found in other vertebrates. The abdominal segment is located at the trunk’s front. The abdominal cavity is the area occupied by the abdomen. This section contains most of the organs.
Hip can refer to an anatomical joint, or a specific region in the vertebral anatomy. This area is located in the iliac region to the femur or thigh bone, and is inferior to the lateral crest to the gluteal. Three of the bones in the pelvis are fused to the hip bone in adults.
The buttocks, or fleshy portion of most mammals’ exterior anatomy, are located in the posterior region of the pelvic area. The buttocks of the human body are located between the lower back (and the perineum) The buttocks carry all the weight of the body while seated and help to take the body’s excess weight off.
The hand is a multi-fingered,prehensile palm that lies below the forearm of primates like humans, monkeys and chimpanzees.
The wrist can be described in human anatomy as either the carpus (or carpal) bones. It is composed of eight carpal bones and a proximal segment of the skeletal. The carpus surrounds the anatomical area, including the forearm, the proximal metacarpus, and five metacarpal bones.
The thumb is considered the first digit in the hand. The thumb is the outermost digit when a person is in the medical anatomic position. It is made up of two phalangeal bone.
The finger is both a limb and a type digit. It allows for manipulation and sensory input in the hand. Five fingers are the norm for humans. The bones found in the fingers, called phalanges, are the bones of the fingers. The thumb, index finger, middle finger, ring finger and little fingers are the names of the fingers.
The knee connects the femur bone to the tibia bone and the patella bone. Also known as the kneecap. These two bones are kept connected by the knee. The leg is only slightly bent backwards due to the patella bone, which is triangular-shaped.
Calf refers to the lower leg’s back. The posterior portion of the leg corresponds to the muscles in the calf according to human anatomy. Calf muscles are the largest muscle in this compartment. The ankle, knee, and toes are the attachments for smaller muscles.
In general, the leg is the whole limb of the body. It includes the toes and foot, calf, thigh, hip, gluteal, and thigh. It can be used to stand, as well as for running and dancing. The hip angles and hip anteversion of female legs are greater than those of males. However, the lengths of the femurs and tibials in males is shorter.
Anatomically, the foot is a common structure in vertebrates. It is the terminal part of a limb that supports weight and allows for locomotion. It is composed of five segments from the metatarsal bone.
The bulge at the heel of the foot is called the heel. It is formed by the projection of one bone, the calcaneus or heel bone. It is located behind the junction of bones in the lower leg.
The toe is the foot’s digits. It is a part or the foot that has five toes. Each toe contains three phalanx bones called the proximal and middle bone. The big toe is not included. It only has two phalanx bone – the proximal & the distal.
If you could “break down” the human body to the microscopic level, the cell would be the most fundamental unit of life.
An average adult has between 30-40 trillion cells. Every day, an estimated 242 million new cells are created. A tissue is formed when a group of cells have similar functions comes together.
Tissues combine into organs, systems, and ultimately, an organism.

- Key Points About the Human Body
There are many movements that the human body can perform, including running, jumping, crawling, walking and bending. The skeleton is the framework that allows us to perform all of these activities. The average human has 300 bones when they are born. As we age, however, our bones begin to fuse. The number of bones in adulthood is 206.
Many vital organs, such as the heart and lungs, are protected by the skeleton. Ligaments, which are fibrous connective tissues that attach bones to each other, allow bone to be attached to another bone.
The points where two bones meet are called joints. They allow for a variety of movements such as rotation, abduction and adduction, protraction and retraction. On the basis of mobility and flexibility, joints can further be classified as movable and immovable. Movable joints can be moved, while fixed joints (also known as fixed joints) cannot. This is because the bones are fused.
Muscles are specialised tissue that aid the bones in locomotion. Through tendons, muscles are connected to the bones. The contraction and relaxation of the muscles in the area that correspond to the movement of limbs causes them to move. Although joints help with flexibility, a bone can’t be bent or stretched unless a muscle uses it. The muscles attached to a bone pull it in the desired direction.
Additionally, the majority of movement is performed by muscles that work together. When we bend our arms, the muscles in the region that supports the movement contract and become shorter and more stiffer. To relax (stretch), the muscles in the opposite direction must pull the bones towards themselves.
- The human body is made up of a head, neck, and four limbs connected to the torso.
- The skeleton is what gives the body its shape. It is made of bone and cartilage.
- The skeleton system houses the internal organs of the human body, such as the heart, brain, and lungs.
- The spinal cord links the brain to the rest of the body.
Different organ systems can be found in different cavities within the human body.
- The skull’s cranial cavity protects the brain as well as other parts of central nervous system.
- The pleural cavity protects the lungs.
- The intestines, liver, and spleen are all located in the abdominal cavity.
Although humans have evolved independently from other animals, our common ancestor is a distant one. This means that we have a body plan similar to other organisms with only the bones and muscles in different amounts.
We might think that giraffes are more vertebrae-rich than humans. Despite being so tall, giraffes still have the same number vertebrae as humans. They also have seven vertebrae in the neck.
One of the most distinctive characteristics is our ability to use our hands. This is especially important for tasks that require dexterity such as opening bottles of water, opening doors, and writing.
This is due to the fact that humans have ancestors who walked on their hind legs rather than all four. The dissection of corpses (cadavers) was the best way to gain anatomical insights about the human body. Although it was quite a grueling affair, it was the basis of much medical literature for centuries. Today, technology innovation makes it possible to examine human anatomy at a microscopic scale.
Scientists continue to discover organs that have previously been overlooked or mistakenly identified with other tissues. Scientists discovered the Interstitium, a new organ that spans the entire body and is located under the skin in 2018.
It refers to the biochemical, physical, and mechanical functions of human beings. This link health, medicine, science in a way which studies how the body adapts to stress, physical activity, and diseases.
A physiologist is a person who has been trained to study human physiological processes. For his outstanding research, Claude Bernard is known as the father in Physiology.
The Human Body and its Parts
As the definition of an organ remains controversial, so does the list of human body parts. There are a total of 79 organs that have been identified so far. There are also organs that have “lost their function” during evolution. These organs are known as vestigial organs.
Some organs are connected and can form systems that specialize in a particular function or set of functions. These organs are collectively known as organ systems.
Five of the 79 organs are vital for survival. Any damage to any of these organs could lead to death. The brain, heart and liver are five of the most important parts of the human body. Continue reading to learn more about each body part and how they function.
- Systemic circulation
- Circulation in the lungs
There is also a third type, called Coronary circulation. Blood is the connective tissue of the body and helps transport nutrients and minerals to cells. It also helps remove waste byproducts.
It is also known by the body’s “transport network. “Human heart is identical to other vertebrate hearts and is therefore homologous.
The digestive system is responsible for breaking down foods and assimilation of nutrients into the body. This information is then used by the body to grow and repair cells.
These are the major components of your digestive system:
- Gastrointestinal tract
- Both small and large intestines
Mastication is the first step in digestion. Next, saliva is mixed with the food to form a bolus. This small, round mass can then be swallowed easily. Once the food is swallowed, it travels down the oesophagus to the stomach. The stomach produces strong acids and powerful enzymes to break down the food into a paste.
The bile is then secreted from the liver and powerful digestive enzymes released by the pancreas. This is where nutrients are absorbed from food.
The stool and other leftovers are then moved to the large intestinale, where they transform from liquid to solid as water is removed. It is then pushed into the Rectum and ready for elimination.
The human reproductive system, also called the genital or genital system, is a system of internal and external organs that aid in reproduction. It is different for males and women. The reproductive organs can function with the help of hormones, fluids and pheromones.
Female Reproductive System
The following are the components of a Female reproductive system
- Ovaries: Female egg and the hormone estrogen are produced by the ovary.
- Uterine tubes : Other names for uterus tubes include fallopian tubes or oviducts.
The uterus, also known as the womb or the womb is a pear-shaped organ that houses the fetus. The gateway for sperm to enter is through the cervix, which leads to the vagina. The vagina is the entry point for the penis during intercourse, and the exit route for the fetus at delivery.
Male Reproductive System
The male reproductive system consists of testicles, which act as a storehouse for sperms. These organs are enclosed in a pouch called scrotum.
The vas deferens, which are the accessory ducts of the male sexual system, is located next to the testis. The fluids produced by the seminal glands and Cowper’s gland mix the sperm with fluids. Cowper gland’s primary function is to increase the volume of semen and to provide lubrication during coitus.
The respiratory process is the inhalation of carbon dioxide and the intake of oxygen. This system is also called the ventilatory, gas exchange or respiratory apparatus. Vertebrates like human beings possess lungs for respiration. The cycle of exhalation and inhalation is the basis of respiration.
Inhalation allows for oxygen to enter the body, while exhalation causes carbon dioxide to leave the body. The following organs make up the respiratory system:
Diffusion allows molecules of oxygen and carbon dioxide to be exchanged passively between blood cells and the external environment. Alveoli, which are the air sacs in the lungs, facilitate this exchange.
The central nervous system manages and maintains voluntary and involuntary actions. It is responsible for channeling the signals from and to different parts of the body. The Nervous System can be broadly divided into two types:
- Central Nervous System
- Peripheral Nervous Systems
The brain and the spinal cord are part of the central nervous system. The peripheral nervous system is composed of nerves and ganglia outside the brain and spinal chord. Every part of the body is connected by the axons.
The Central Nervous System is composed of :
- Forebrain : It includes the cerebrum and hypothalamus. The cerebrum is the largest part of the brain. This section of the brain is responsible for the majority of cognitive functions, including perceiving, controlling motor function and receiving and processing information. The fore-brain also supports sexual development and emotion functions.
- The midbrain : It’s located between the hypothalamus (thalamus) and thalamus. The midbrain is responsible for the brain stem. The mid-brain controls both visual and auditory responses.
- Hindbrain : The hind-brain ties the cerebellum, pons and medulla together. The Hind brain is responsible for interconnecting different brain parts that help to accommodate neurons and link them to the spine column.
The Peripheral Nervous System is composed of :
- Somatic nervous system : Its primary function is to transmit motor and sensory impulses back and forth between the CNS. It is connected to all sensory organs, limbs, and skeletal system. Imagine yourself riding a bicycle and suddenly spotting a dog or another obstacle on the road. The somatic nervous system is responsible for your ability to quickly steer out of the path of an obstacle and avoid a crash.
- Autonomic Nervous Systems: The system works automatically and without any effort on the part of the individual. It relays impulses from the central nervous to smooth muscles and involuntary parts such as your heart, lungs, etc. It prepares the body for any severe attacks or abnormal conditions, such as high body temperatures during fever or increased blood pressure and breathing after strenuous exercise.
Cells are the basic unit of life. They make up every human being, tissue, organ system, and human body part. Anatomy refers to the science of understanding and describing the structure and parts of living organisms. Physiology is concerned with the inner mechanisms and processes that support life.
These include the biochemical and physical interactions among various factors and components of our bodies. As evolution progressed, organisms developed advanced features and characteristics that allowed them to thrive and be more efficient in their environment.
Human structure can be described bipedally. It has hair covering the body and mammary glands. The body has a special circulatory system that allows for efficient transport of nutrients and materials.
A well-developed digestive system is essential for the body to obtain all of its nutrients and minerals. A healthy respiratory system allows for efficient gas exchange. The nervous system facilitates coordination and interaction within the body as well as with the outside environment. This is essential for survival.
