Question

The large surface area in the gut directly facilitates _____.

Answer 1

Answer:

B. Absorption

Explanation:

• Absorption is a process that takes place in the small intestines or ileum of the GI tract, in which simple and soluble nutrients are absorbed into the blood stream.
• Absorption is enhanced by several adaptations of the gut such as large surface area of the gut which directly facilitates absorption of nutrients.
• Presence of villi and microvilli in the gut increases the surface area for absorption of nutrients in the ileum.
