Ileum
Description
The Ileum is a coiled, mobile segment that accounts for 60% of the length of the Small Intestine - it is the lowest of the three portions of the Small Intestine.
Biological Functions of the Ileum
Digestive System
The Ileum continues the process of Digestion - food particles that have not been absorbed by the time they reach the end of the Ileum (the Ileocecal Valve) are “emptied” into the Cecum of the Colon. The Ileum is the site of absorption of several nutrients including:
Bile Salts and Bile Acids
Essential Fatty Acids
Fat-Soluble Vitamins
Folic Acid
Vitamin B12
Water
These Substances Enhance the Function of the Ileum
Enzymes
