Front

What is the main function of the Digestive System?

Back

The Digestive System is responsible for breaking down food into nutrients that can be absorbed by the body.

Front

What are the two types of digestion?

Back

Mechanical digestion and chemical digestion.

Back

Nutrient absorption occurs in the villi of the small intestine.

Front

What is the function of the Respiratory System?

Back

The Respiratory System is responsible for taking in oxygen and expelling carbon dioxide.

Front

What is the process of gas exchange in the lungs called?
