THE STRUCTURE OF THE HUMAN BODY

The structure of the human body

A human is a living organism. In biology, a human belongs to the group of animals and more specifically to vertebrates (animals with a backbone).

Humans are mammals, which means they are warm-blooded, they have hair, and mothers feed babies with milk.

Humans are also primates, a group that includes monkeys and apes. They have forward-facing eyes, flexible hands, and a well-developed brain.

Humans belong to the species Homo sapiens. This species is known for advanced thinking, language, and complex social life.

Humans can learn, plan, invent tools, and pass knowledge from one generation to the next.

The human body is made of many systems that work together:

• The nervous system helps us think and react.
• The circulatory system carries blood.
• The respiratory system brings oxygen into the body.

All these systems support life, growth, movement, and survival.
