Because it takes time to absorb food.
It is large because of the tiny villi which are inside the small intestine. The intestine needs to be big for these tiny things to extract all the nutrients and put them into the bloodstream for energy.
The small intestine is where absorption of glicids, lipids and proteins occur. The absorption of these nutrients is slow and envolves complex processes. Differently, the large intestine function is to uptake water and ions which is a much faster process.
Thus, small intestine needs to be longer.
the longer it is the more the oppurtunity to absorb more and more nutrition
Because the majority of digestion takes place in the small intestine, therefore the longer it is, the longer the body can take to absorb nutrients from the food.
The blood was in the small intestine.If the small intestine is straight, the blood would not absorb the food
The villi need a large surface area so they can absorb the food
The long length of the small intestine assure the complete absorption of the nutrients.
the large intestine is 1.5 meters long, while the small intestine can be from 4-7 meters long. Though it is called the small intestine, it is actually the longest part of the digestive tract.
The small intestine is about 7 meters long.
An adult small intestine is close to 22 feet long.
HOW LONG IS AN ADULTS SMALL INTESTINE?
i dot know
Three times as long. The small intestine is 21 feet long and the large one is 7 feet long.
small intestine
The small intestine of a koala is smaller than its caecum, which is up to 2.5m in length and connects the small and large intestines. The small intestine itself is about one metre long.
The smaller intestine is larger because it is 20 feet long and the large intestine is only 5 feet long
that's just how ur body is made
The small intestine, while longer than the "large" intestine, is smaller in diameter and circumference, comparatively, to the large intestine.
In adult humans, the small intestine is around 7m long, and about 3cm wide. The large intestine is about 1.5 metres long and around 6-10cm wide. The large intestine is called 'large' because it is wider than the small intestine, it is not longer.
