Digestive System
The digestive system is in charge of making food
energy for our bodies.
Digestion begins in the mouth when we chew the food. This
is mixed with saliva forming the food bolus.
The food bolus passes through the pharynx and
esophagus to the stomach where digestion will continue. Thanks to the gastric
juices that are capable of undoing it.
Next it goes to the small intestine and then to the
large intestine. The water and nutrients that our body needs are absorbed in
the intestines.
The capillaries of the circulatory system that
surround the intestines collect nutrients and distribute them throughout the
body.
Finally, the solid remains that have been left over
from the digestion are eliminated through the anus.

different parts of the digestive system, and what is the main function of each
part?
