Question

Large intestine in man mainly carries out
(a) absorption
(b) assimilation
(c) digestion of fats
(d) digestion of carbohydrates

Answer 1

The large intestine in man mainly carries out absorption (option a).

The absorption process in large intestine can be described as follows:

• In the digestive system or digestive tract, the large intestine is the final site of absorption.

• The large intestine absorbs water and vital nutrients from the chyme, a partially digested food that comes from the small intestine.

• The peristaltic waves help to absorb these substances at ascending and transverse colon of the large intestine.

The other options are incorrect because:

1. Assimilation is the process by which cells take up digested food.
2. Digestion of fat occurs in the stomach and small intestine
3. Digestion of carbohydrates takes place in the mouth and small intestine.

• Hence, the large intestine mainly performs the function of absorption.

Answer 2

Answer:

Absorption
