digestion process
Breaking down food
The digestion process is the breakdown of food into nutrients the body can absorb.
It begins in the mouth with chewing and enzymes, continues in the stomach with acid and churning, and completes in the intestines where nutrients pass into the bloodstream.
The digestion process takes several hours depending on what you've eaten.
