Digestive describes anything related to digestion, the process your body uses to break down food into nutrients it can use. Your digestive system includes your stomach, intestines, and other organs that work together to turn a sandwich into energy and building blocks for your cells.

When you eat an apple, your digestive organs spring into action. Your teeth start the work, then your stomach churns the pieces with powerful acids, and your intestines extract vitamins, sugars, and other nutrients. What your body can't use eventually leaves as waste.

You might see digestive biscuits in a grocery store. These cookies got their name because people once believed they helped with digestion, though modern versions are really just lightly sweet crackers. Some people take digestive enzymes, special proteins that help break down food, when their bodies have trouble doing this naturally.

When something upsets your digestive system, like eating too much candy or catching a stomach bug, you might feel nauseated or get a stomachache.
