Digestive System
Respiratory System
Circulatory System
The human body is made up of a number of systems. Each
system performs a certain function. For example, the digestive
system digests and absorbs food, the respiratory system carries
out the process of breathing and the circulatory system distributes
the digested food and oxygen all over the body cells. The urinary
system helps the body get rid of harmful substances, the nervous
system lets us have the ability to feel, hear, see, smell, and taste,
where as the reproductive system makes us give birth for new
individuals who will look like us. And all these systems are
working in full harmony and integrity together to keep the human
life goes on.
Let's study the digestive system together to know How this
system are structured.
