Approximate Length of the Large Intestine:
The large intestine, also known as the colon, is the final part of the digestive system. It plays a crucial role in absorbing water and electrolytes, forming and storing feces, and eliminating waste from the body.
To answer the question regarding the approximate length of the large intestine, we can consider the following points:
1. Anatomy of the Large Intestine:
- The large intestine is divided into four main parts: the cecum, colon, rectum, and anal canal.
- The colon is further divided into several sections, including the ascending colon, transverse colon, descending colon, and sigmoid colon.
2. Length of the Large Intestine:
- The total length of the large intestine varies among individuals.
- On average, the large intestine is approximately 1.5 meters long.
- The length can range from 1.2 meters to 1.8 meters.
3. Absorption of Water and Formation of Stool:
- The large intestine absorbs the majority of water from the remaining undigested food material.
- This absorption process helps in the formation of stool, as water content is reduced and the feces become more solid.
Therefore, the correct answer is D: 1.5 m, as it represents the approximate length of the large intestine.
