The Digestive System
Did you ever wonder how the food we eat breaks down into smaller pieces? This is the work of the different organs of our digestive system. The substances which are needed by our body cannot be absorbed into our blood until they have broken down further into smaller pieces.
The digestive system is composed of the mouth, esophagus, stomach, small intestine, and large intestine. These organs work together to break down the food we eat into smaller pieces for the use of our body.
