Cow Intestines.

I’m back!  And none the worse for wear.  Today I’m here to talk about a very interesting subject, cow intestines.  A cow’s intestines are made up of three different organs.  The small intestine, the cecum, and the Large intestine.  The small intestine measures about 20 times the length of the animal. It is composed of three sections: the duodenum, jejunum, and ileum. The small intestine also receives the secretions of the pancreas and the gallbladder, which aids digestion. Most of the digestive process is completed here, and many nutrients are absorbed through the villi (small finger-like projections) and into the blood and lymphatic systems.  The cecum is a large area located at the junction of the small and large intestine where some previously undigested fiber may be broken down. Although the complete function of the cecum has not been established.  And the large intestine is the last segment of the tract through which undigested feed passes. Some bacterial digestion of undigested feed occurs, but absorption of water is the primary digestive activity occurring in the large intestine.  Isn’t it interesting how long the intestines are?  Though I imagine that it takes a lot of work to break down and get nutrients from what a cow eats.
