Question

The major part of absorption is carried out by (i)______ through (ii)_______ of microvilli by different mechanisms, namely (iii)________ and (iv)______.

• A. i. Jejunum ii. Enterocytes iii. Passive absorption iv. Active absorption
• B. i. Ileum ii. Lacteals iii. Diffusion iv. Active absorption
• C. i. Duodenum ii. Capillaries iii. Active absorption iv. Osmosis
• D. i. Large intestine ii. Ceacum iii. Reverse Osmosis iv. Passive absorption

Answer 1

The correct option is A i. Jejunum ii. Enterocytes iii. Passive absorption iv. Active absorption

Jejunum, through enterocytes of microvilli, carries out the major part of absorption by different mechanisms, namely passive absorption (eg. fructose), if they can be absorbed without any use of energy and active absorption (eg. glucose), if they require energy for absorption
