Most of the end products of digestion are absorbed from the small intestine into the hepatic portal venous system.
Blood coming from the hepatic portal venous system is "treated" by the liver before being sent to the heart for circulation.
Water and any previously unabsorbed digestive end products are absorbed from the large intestine into the blood.
Waste materials from the digestive process are eliminated from the large intestine, through the anus, in the form of feces.
The reticuloendothelial system provides protection in the digestive system.
It encompasses lymphoid tissue in the tonsils, small and large intestine, and the Kupffer cells in the liver.
After the birth of a baby, colostrum, the initial secretion from the mammary glands, is filled with antibodies.
The mammary glands respond to infection, in reflux from the feeding baby, by producing the appropriate antibodies.
