Digestion System Process
- The mouth chews the food.
- Saliva mixes the food.
- We swallow the food and it goes to the esophagus
Digestion
in the stomach
- The stomach produces gastric juices.
- The gastric juices break up the food into a pulp.
Digestion
in the small intestine
- The liver, the pancreas and the intestine produce juices.
- These juices mix with the pulp.
Absorption
·
The
small intestine does the absorption (it carries the nutritional substances to
the blood and the blood carries these substances to all parts of the body).
Excretion
·
After
the absorption, the pulp goes to the large intestine.
·
The
parts of the food that cannot be used by the body are turned into feces (poop).
- These feces are expelled from the body through the anus.
Here you have the link of the video and it's explanation:
The video explains that the process of digestion
starts in the mouth were we chew the food and mix it with saliva. Through the
esophagus the food arrives to the stomach were it's mixed with the gastric
juices forming pulp. Then, in the small intestine the pulp is mixed with the
juices of the liver and the pancreas. After, the small intestine absorbs
nutrients to the blood (absorption). The food that the small intestine doesn’t
absorb passes to the large intestine, and finally it is expulsed in form of
feces through the anus.
