Overview

The digestive and the excretory systems take the food we eat through a marvelous maze. Every bite travels from the mouth to the stomach to the intestines. Food is separated into nutrients and waste products, which both systems expel. Along the way, the digestive system mashes, chops, crushes, dissolves, and breaks down the food into molecules of nutrients. These provide energy to the rest of the body. The excretory system filters the blood and regulates the amount of salt and water in the body. Learn how these remarkable systems work together to bring us life-giving nutrients and rid our bodies of waste.
