As we know that large intestine is smaller than small intestine so why...
Well, small intestine is about 6—7 metres long, but its diameter is about 2.5 cm. It's called small intestine because the diameter of large intestine is about twice that of small intestine. So the name is based on the size of diameter, not the length.
As we know that large intestine is smaller than small intestine so why...
Why is the large intestine called "large"?
The large intestine, also known as the colon, is called "large" not because it is physically bigger in size compared to the small intestine, but rather due to its wider diameter. The large intestine is wider in diameter than the small intestine, which gives it the name "large" in comparison. Let's delve into more details to understand this further.
Structure and Function of the Intestines
The intestines are a part of the digestive system, responsible for the absorption of nutrients and elimination of waste from the body. They are divided into two main parts: the small intestine and the large intestine.
1. Small Intestine: The small intestine is the longer of the two and consists of three sections - the duodenum, jejunum, and ileum. It plays a vital role in the absorption of nutrients from the digested food.
2. Large Intestine: The large intestine is shorter, wider, and located towards the end of the digestive tract. It consists of the cecum, colon, rectum, and anus. The main function of the large intestine is to absorb water and electrolytes from the remaining indigestible food matter, consolidate the waste into feces, and eliminate it from the body.
Diameter Comparison
The small intestine has a smaller diameter compared to the large intestine. However, the length of the small intestine is much greater than that of the large intestine. The small intestine is approximately 20 feet long, whereas the large intestine is about 5 feet long.
The small intestine is around 1 inch in diameter, while the large intestine is wider, varying between 2-3 inches. This increased diameter of the large intestine allows it to accommodate a larger volume of fecal matter as it moves through the colon.
Conclusion
In summary, the large intestine is called "large" because it has a wider diameter compared to the small intestine. This wider diameter allows it to accommodate a larger volume of fecal matter as it prepares for elimination from the body. While the term "large" may seem misleading, it refers to the relative size of the large intestine in comparison to the smaller diameter of the small intestine.
