What breaks down food and absorbs the nutrients?

The digestive system is responsible for breaking down food and absorbing the nutrients. The mouth, stomach, and small intestine are the main organs involved in this process. The mouth breaks down food through chewing and saliva, while the stomach breaks it down further through churning and stomach acid. The small intestine is where most of the absorption of nutrients occurs, with the help of bile and enzymes from the liver and pancreas.
