The human body consists of ten main systems that work together to keep the body functioning properly. The document lists and briefly describes each of the ten systems: integumentary, skeletal, muscular, digestive, circulatory, respiratory, nervous, excretory, endocrine, and reproductive. Each system plays a vital role in maintaining the health and well-being of the entire human body.

Systems

2. The Human Body Systems
 The human body is the entire structure of
a human organism. It consists of a head, neck, torso,
two arms and two legs. The average height of an adult
human is about 5 to 6 feet tall.
 By the time the human reaches adulthood, the body consists
of close to 100 trillion cells, the basic unit of life. These cells
are organized biologically to eventually form the whole body.
 The human body is made to stand erect, walk on two feet,
use the arms to carry and lift, and has opposable thumbs
(able to grasp).

3. The Human Body Systems
 Although viewed as
whole, the human body is
actually made up of ten
different systems.
 Each of these systems
plays a vital part in the
health and well being of
the entire body.
