Basic Facts
The spider monkey is in the class Mammalia. An adult spider monkey usually grows anywhere from 40-50 cm. This monkey's habitat consists of tropical jungles in South America. This monkey mainly feeds on fruits, berries, insects, and small reptiles. Their main predators are jaguars, pumas, ocelots, and large snakes. Spider monkeys have become an endangered species due to deforestation and constant hunting from their predators.


Organ System
Monkeys are primates, just like humans are. For this reason, they have a similar organ system. The organ system that is described is the digestive system. The food that these monkeys ingest pass through their mouth, down their esophagus, is filtered by the liver, is digested in the stomach, becomes converted into energy by the pancreas, passes through small intestine to absorbed nutrients and minerals, passes through the large intestine to absorb water, goes through rectum and leaves through anus.


Organ: Intestines
90% of digestion takes place in the intestines.
-The small intestine is responsible for absorbing most of the nutrients from what we eat and drink.
-The large intestine is in charge of absorbing water from the remaining digestible waste and expels the remaining waste.

-Tissues in the small intestine include:  the epithelial layer, the submucosa, smooth muscle, and the outer layer known as the visceral peritoneum(commonly known as the serosa).

-Tissues in the large intestine include: the mucosa and muscularis mucosa. The large intestine also includes a simple column epitheleum with goblet cells.




Epithelial Tissue Layer
-This layer covers the surface of the small and large intestines with epithelial cells.
-The cells are packed very tightly.
-This tissue does not have any blood vessels.
-The tissues also contain goblet cells.

Epithelial Cells
Epithelial Cells contain microvilli that are in charge of absorbing nutrients in the intestines. These cells are so small and tightly packed, which drastically increase its surface, and therefore increases their absorption effectiveness. The layer of epithelial cells is very thin, so nutrients are absorbed even quicker this way. Epithelial cells are not only located in the intestines, but they cover all of the body organs as well.
