Question

Absorption of glucose and amino acids is a simple process. It is mostly carried out by the villi of small Intestine; In reference to the process, choose the correct (option) path.

• A. Villi $\to$Portal System $\to$ Blood $\to$ Body parts
• B. Portal System $\to$ Blood $\to$ Body parts $\to$ Villi
• C. Blood $\to$ Body parts $\to$ Villi $\to$ Portal System
• D. Body parts $\to$ Villi $\to$ Portal System $\to$ Blood

Answer 1

The correct option is A Villi $\to$Portal System $\to$ Blood $\to$ Body parts

All the digested products (glucose, amino acids, triglycerides, nitrogenous bases etc) are absorbed by enterocytes of villi and are transported to the portal system to the liver and thereafter, they are distributed by the blood to all the body parts. Any excess nutrients are retained in the liver and are converted to glycogen and other products. The correct path to represent the process is

A. Villi $\to$ Portal System $\to$ Blood $\to$ Body parts.
