Question

in which organ does most absorption take place? select one a. small intestine b. large intestine c. liver d. gallbladder e. stomach

Explanation:

To determine the organ where most absorption occurs, we analyze each option:

• Option A (Small intestine): It has a large surface area (due to villi and microvilli) and is the primary site for absorbing nutrients like carbohydrates, proteins, fats, vitamins, and minerals.
• Option B (Large intestine): Absorbs water, electrolytes, and some vitamins, but not the majority of nutrients.
• Option C (Liver): Processes nutrients after absorption, not the main absorption site.
• Option D (Gallbladder): Stores bile, no absorption function.
• Option E (Stomach): Primarily for digestion (acid breakdown, enzyme action), minimal absorption (some water, alcohol).

So the small intestine is the main absorption organ.

Answer:

A. Small intestine
