The length increases the surface area so that it can better absorb nutrients.

The length ensures that enough digestive juices are available to break down food.

Answer 1

The length increases the surface area so that it can better absorb nutrients.

Step-by-step explanation:

In this problem, we need to study the effect of the length of the small intestine to assist digestion. Firstly, we introduce the small intestine definition and functions.

The small intestine is one of the most important parts of the intestines where 90% of the digestion and absorption of food occurs. The main function of the small intestine is the absorption of nutrients and minerals from food.The small intestine is good for absorption since it has a large inner surface area, as the surface area increases it can better absorb nutrients.

Finally, we can conclude that The length increases the surface area so that it can better absorb nutrients.
