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: -These villi are also full of microscopic hair-like structures called microvilli. Villi and microvilli help increase the surface area of the small intestine which supports optimum absorption of nutrients from the digested food.
Detailed explanation-3: -The surface of the small intestine has a finger-like microscale villus structure, which provides a large surface area to realize efficient digestion and absorption.
Detailed explanation-4: -Formation of finger-like structure follows two processes: pore initiation and growth. As a polymer solution undergoes a liquid-liquid phase separation, both polymer-rich and polymer-lean phases are developed. The nuclei of the polymer-lean phases initiate the finger-like structure.
Detailed explanation-5: -(in-TES-tih-nul VIH-ly) Tiny hair-like projections that line the inside of the small intestine. They contain blood vessels and help absorb nutrients.
