SMALL INTESTINE

• The small intestine is the primary organ of digestion and absorption.
• Anatomically, small intestine is divided into three segments viz. Duodenum, jejunum and ileum.
• Duodenum originates at the distal end of the gizzard.
• It is difficult to differentiate the jejunum from the ileum in birds and these two segments are collectively called as lower intestine.
• Most of the chemical enzymatic digestion and absorption of nutrients and transfer of nutrients from gut into blood and lymphyatic system takes place in the small intestine.
