Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which organ helps increase the surface area for better absorption of the nutrients?
A
oesophagus
B
rectum
C
villi
D
small intestine
Explanation: 

Detailed explanation-1: -The lining of the small intestinal mucosa is very highly specialized for maximizing digestion and absorption of nutrients. The lining is highly folded to form microscopic finger-like projections called villi which increase the surface area to help with absorption.

Detailed explanation-2: -Small intestine absorbs food nutrients through villi. The small intestine which is also known as the small bowel is an organ within the alimentary canal, in which most of the end absorption of minerals and nutrients from food takes place.

Detailed explanation-3: -Villi are covered with even smaller hairlike structures called microvilli. Microvilli projections are smaller than villi. Their job is to also increase the surface area so each villus can absorb the maximum amount of nutrients.

Detailed explanation-4: -Villi are small finger-like projections present in the inner lining of the small intestine. They increase the surface area of small intestine by providing more area for efficient absorption of nutrients. The presence of villi and micro-villi gives a brush border appearance.
