Question

What is the main role of large intestine?

• A. Produce enzyme for digestion
• B. Assimilation
• C. Absorb water
• D. Produce bile

Answer 1

The correct option is C

Absorb water

The large intestine consists of three regions; caecum, colon, and rectum. The large intestine does not secrete any enzyme. It mainly absorbs water from the undigested food. After most of the water is absorbed, the undigested food reaches the rectum and is egested out through the anus.
