The digestive system

thethr

Digestive system is very important because it can turn the the food we eat into nutrients that are the right size to reach our cells and be absorbed and it also gets rid of elements we don't need.

Ingestion

Ingestion occurs when food enters the digestive tract through the mouth. Teeth helps break down the food into smaller pieces and saliva softens the food and the tonge rools food into a ball called bolus. the bolus goes into the rest of the digestive system.

Digestion

The bolus moves to the stomach where the gastric juices are, the bolus turns into a thick, acid liquid called chyme. The chyme travels to the intestines where the chyme turns into a milky fluid called chyle, the chyle contains water, nutrients, and undigested food. The undigestive food goes to the large intestine where it leaves the body.
