the skeletal and muscular systems:

The adult skeletal system is a framework of 206 bone

• Hold the body together
• Give it shape
• Protect organs and tissues

The skeleton also provides anchore points for the muscular system, wich includes three types of muscles found throughout the body and facilitate movement :

Digestive System:

It is an approximatly 9 meters series of organs that covnert food into fuel .food enters the system through the mouth and then moves into the esophages ,the stomach and the intestins.Nutriments are absorbed into the body while the solide waste expelled through the anal canal the end of the digestive tract .

Digestive System Structures

reproductive system:

Nomatter the role, size or shape of the body systems each began with a reproductive system .This system is responsible for creating life .The primary organs envolved between the sexes are:

• Ovaries, Fallopian Tubes and vagina found in woman .
• Testes and sperm channel found in man .

Together fertilization may occur organ systems form and a child is born.
