The human body is the form in which homo sapiens appear and are able to function in the environment. The size, shape and proportions of a person's body are based on the structure of bones, muscles, tissues, and cells within the body but also upon his or her inherited genetics. The human body is able to protect itself due to its strong bones and immune system, however, it is still able to fall prey to disease and injury.

Human Body Background

The anatomy of the body is a result of the evolution of primates into homo sapiens. The structure, appearance and function of the human body are based on the evolved genetics over centuries. Though this form has not changed considerably since the dawn of homo sapiens, the understanding of the human body and its features continues to grow and delve deeper into the construction of each body part and its function.

Human Body Diagram

The human body diagram is essentially a map of the body that identifies different structure and organ systems within the body. This diagram differs based on the gender of person shown as female human body pictures will differ from those of the male human body. This diagram may be general and show multiple structures and systems or it may be specific to one organ system and display its related components.

Human Body Parts

The features of the body, whether superficial or internal, are known as the human body parts. These structures perform various activities based on their construction and components. For example, hands are able grasp items as they possess opposable thumbs, muscles and ligaments. Other human body parts are not mobile but are still able to perform important tasks such as the brain which is housed in the numerous bones of the cranium.

Human Body Systems

The various human body systems are responsible for the different life processes such as respiration, reproduction and movement. These systems, also known as organ systems, operate based on the connections between organs and other internal structures to allow for these processes to be carried out. One system may incorporate a large number of organs in order to carry out these processes, such as the digestive system which is quite extensive.

Muscles of the Human Body

The muscles of the human body provide people with strength and the ability to move and function. Muscles are not only found on bones, but also internally as they facilitate the movement of interior structures along different organ systems. The muscles in the human body function by contraction and releasing muscle fibers which allow for movement and the ability for humans to push and pull objects along with other tasks.

Human Body Organs

The organs of the human body are responsible for carrying out the different life processes that make human life possible. These organs are organized based on the system of which they are part in order to carry out these processes. As with muscles, human body organs are composed of both cells and tissues in order to develop a fully functioning organ. There are approximately 22 organs in the human body which keep a body healthy and active.

Bones in the Human Body

There are approximately 206 bones in the human body and each serves a different task based on its size, density and location within the body. While bones allow for the body's structure, they allow provide strength and rigidity for the body. Furthermore, the bones of the human body offer protection from injury for the organs housed in the body and other structures.

Human Body for Kids

Information on the human body for kids is available in many forms, ranging from books to online interactive tools. This data is designed to be child friendly based on the language used and the information provided in order to be easily understood at different age levels. One such tool is The Human Body Book which provides updated information and images for both children and adults to help them comprehend the different structures and functions of the human body.

Cells in the Human Body

The cells in the human body are the smallest parts of the body as they compose each other structure found with humans and other forms of eukaryotic life. There are approximately 100 trillion human body cells within adults though there are hundreds of variations depending on the location and function of a cell. The classification of a cell is determined by where it is found in the body, its size, shape and responsibility.

Human Body Chart

The human body chart is a visual aid that displays the human form and its various organ systems. This device is often used by teachers and doctors alike in discussions of the human body and its parts while providing visual assistance in order for people to learn more. Related to his visual aid is the human body model which is an interactive physical tool which is a likeness of the human form that can be manipulated for the learning process.
