Absorption of food nutrients in monogastric animals

• Absorption is the process by which digested food from the lumen of the intestine is taken into the blood capillaries.
• The main site of absorption is the minute intestine.
• The inner lining of the small intestine has a large no of minute finger-like projections called villi.
• The villi are the unit of absorption that increases the absorption surface.
• Each villus is lined by a single layer of epithelium and suppressed with many blood capillaries and a capillary lymph called a lacteal.
