Transcript of Ruminant System

Around 150 species of animals use
the Ruminant Digestive System in
their diet. Having a Ruminant
Digestive system means that the
animal with the system is a
herbivore. Cows, sheep, and goats are examples of animals that
use the Ruminant System. The main action of the Ruminant system
is to enable the animal to chew more, and further break it down for digestion. The stomach for a Ruminant animal has four compartments! The rumen, reticulum, omasum, and the abomasum. But, it all starts in the mouth... Moo! It begins in the mouth, which does more work than people think. Mastication is no joke, and something most of us know all too well. We chew, we break down enzymes, we absorb, we swallow. But, what about any extra nutrients that might escape our clutches as we chew? This is what Ruminant animals observe, so they basically regurgitate it and chew it some more, to get the most out of their masticating. The Esophagus. A tube like passage; a tunnel, if you will, for a food train to travel through to get to the stomach. It travels down the esophagus, not necessarily by gravity, but by a bunch of muscles pulling it down. Ruminant animals' esophagus's have muscles that pull the food back up as well, to complete their chewing processes. The first chamber of the stomach - the Reticulum!
The inside of the reticulum is honeycomb like, to catch "foreign matter" from the food stuffs. After this, food gets regurgitated back to the mouth, now called "cud". The animal will repeat this process until the food material is small enough to pass through the Reticulum to the Rumen. The Rumen is where smaller food materials
get further broken down; this is where fiber gets
broken down by bacteria. The Omasum is a small, but muscular part of the stomachs. This is where food gets sorta "grinded" and prepared for chemical breakdown. This is the section most similar to normal animals' stomachs. Most of the chemical breakdown of food occurs here, while also mixing in some of those digestive fluids. The Small Intestine, the area where food stuff actually gets absorbed into the blood stream.
