the small intestine has a large surface area because it allows nutrients to be absorbed into the body more quickly and easily.If there was a small surface area may-be most of our nutrients would end uo in the large intestine and out when we go to the toilet. To answer the final part of the question. What contributes? the length and elasticity of the small intestine contributes to it having a large surface area.
Small intestine has lots and lots of villi and microvilli for absorption, large intestine absorbs water and it has lots and lots of goblet cells that produce mucus so it's easier to remove waste (aka poop)
The large surface area of the small intestine is achieved by a combination of anatomical features such as the plicae circularis, the vili, and the microvilli.

The villi on the inner surface.
The villi on the inner surface.
It can cause internal bleeding
folds and villi
To allow a greater surface area for nutrient absorption.
In small intestine. You have very large surface area of the intestine is there for the same.
The small intestine has small tiny projections called "villi". These projections increase the surface area for absorption. The large intestine however lacks these structures.
The answer is small intestine.
The surface area of the small intestine is very large. Some where between 2500 to 3000 square feet. Every thing possible is absorbed, eventually, through such large surface area.
