What is digestive system and its function?

The digestive system breaks down food into nutrients such as carbohydrates, fats and proteins. They can then be absorbed into the bloodstream so the body can use them for energy, growth and repair.

What is the importance of digestive system?

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

What is the digestive system summary?

The digestive system carries out three primary processes: mixing food, moving food through the digestive tract (peristalsis) and using chemicals to break down food into smaller molecules. Consult a health care provider about specific questions regarding how digestion works and any related digestive health problems.
