Which of the following is not the function of Large intestine?

Options

A. (a) Absorption of water
B. (b) Nutrient absorption
C. (c) Secretion of mucus to lubricate faeces
D. (d) Temporary storage of faeces in rectum

Explanation

To determine which of the following is not a function of the large intestine, we will analyze each option provided:

1. **Option A: Absorption of water**
- The large intestine is primarily responsible for the absorption of water from the undigested food material. This process helps in forming solid waste (feces) from the liquid chyme that enters the large intestine from the small intestine. Therefore, this is a function of the large intestine.

2. **Option B: Nutrient absorption**
- Nutrient absorption primarily occurs in the small intestine, where digested nutrients are absorbed into the bloodstream through the villi. The large intestine does not play a significant role in nutrient absorption. Thus, this is not a function of the large intestine.

3. **Option C: Secretion of mucus to lubricate feces**
- The large intestine secretes mucus to help lubricate the feces, making it easier for them to pass through the intestinal tract and out of the body. This is indeed a function of the large intestine.

4. **Option D: Temporary storage of feces in the rectum**
- The rectum, which is the final part of the large intestine, serves as a temporary storage site for feces before they are expelled from the body during defecation. This is also a function of the large intestine.

Based on the analysis above, the only option that does not represent a function of the large intestine is:

**Final Answer: Option B: Nutrient absorption is not a function of the large intestine.**
