How does the body digest food?
assistant
The body digests food by breaking it down into smaller molecules that can be absorbed and used for energy. This process is called digestion, which involves a combination of chemical reactions in the stomach and small intestine. Digestion begins with chewing and mixing food with saliva, which helps to break down starches and proteins into smaller pieces. Then, enzymes in the stomach further break these pieces down into even smaller molecules. Finally, bile from the liver and pancreatic juices help to break down fats into fatty acids and glycerol, which are then absorbed into the bloodstream.
