How The Digestive System
Works
The
four most important parts of digestive system is the mouth, stomach, small
intestine, and the large intestine.
Mouth Food is taken into the body
by the mouth. The teeth bite off little pieces of the food into the throat.
The food goes down the throat, through the esophagus, and to the stomach.
Stomach When the food gets to the stomach
it's in tiny pieces. The stomach has digestive chemicals called pepsin,
gastric juice, hydrochloric acid. The chemicals make it easier for the
body to use the food as fuel. The stomach churns the food around so it
can make it easy to break down the food.
Small Intestine After the stomach, the
food goes to the small intestine. The small intestine chemicals help the
body get nutrients out of the food and put it in the bloodstream. The small
intestine is where the bile comes in to help break so the body can take
in the nutrients. The parts of the food that the body does not need goes
into the large intestine.
Large Intestine The large intestine does
not have any chemicals, and this is where the food the body does not need
goes. The two main parts of the large intestine is the rectum and the anus.
The rectum is where the body turns your waste into a solid. The anus is
where waste leaves the body.
