The human body is a complex, highly organized structure made up of unique cells that work together to accomplish the specific functions necessary for sustaining life.

The human body is the structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organ systems. They ensure homeostasis and the viability of the human body. It comprises a head, hair, neck, torso (which includes the thorax and abdomen), arms and hands, legs and feet.

The human body is made up of all the living and nonliving components that create the entire structure of the human organism, including every living cell, tissue and organ. On the outside human anatomy consists of the five basic parts, the head, neck, torso, arms and legs.

The human body is made up of around 37 trillion cells. The average human heart beats around 100,000 times every day. If you spread out the wrinkles in the brain it would be about the size of a pillow case. Fingernails grow much faster than toenails. They are both made of a protein called keratin.
