The three main functions of the digestive system are:
-
Ingestion: This is the process of taking in food and liquids through the mouth, where digestion begins.
-
Digestion: This involves the breakdown of food into smaller, absorbable components. Digestion occurs both mechanically (chewing and churning) and chemically (enzymatic breakdown of food).
-
Absorption: Once food is digested, the nutrients are absorbed primarily in the small intestine and then transported into the bloodstream for distribution to cells throughout the body.
These functions work together to ensure that the body processes food effectively and obtains the necessary nutrients for energy, growth, and maintenance.
