How is the small intestine adapted for absorption?
Original Khojo Papers practice question — not from a past board paper.
Answer
It is very long, and its lining is folded and covered with millions of villi, each bearing microvilli, giving an enormous surface area. Each villus has a wall one cell thick, a rich network of capillaries and a lacteal, so digested food passes rapidly into the blood and lymph.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
Explanation
Fats are absorbed into the lacteals and other nutrients into the capillaries.
