Simply put, larger surface area allows for more digestive process to occur.
When there is more surface area there are increases in absorption rates as the chyme (the food after it begins digestion) travels through the intestine. The more surface area, the quicker the nutrients and other important things that the body needs will be absorbed into the system.
The inner surface of the small intestine is not flat but thrown into circular folds called plicae circularis. Also, the villi and microvilli help to increase surface area in the small intestine. The increased surface area allows for more area for food absorption.
Small intestines are important site of absorption of digested food. The more is the surface area more is the absorption. Therefore the epithelial lining on the lumen side is folded in finger like projection called villi. These increase the surface area. The cells in the villi also have projection that are called microvilli. They thus increase the area further, facilitating maximum absorption.
There is increased surface area in the small intestine because that is where most of the nutrients from our food are abosorbed. The vilii allow for the most nutrients to be absorbed at one time.
Ville, MicoVille and Mucosal folds
micro villi
Small intestine
The folding of the mucosal membrane increases the surface area of your small intestine, thus allowing more nutrients to be absorbed.
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.
Microvilli are finger-like projections that increase the surface area in the small intestine.
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.
The wrinkles of the small intestine increase its surface area. Increased surface area gives more opportunities for absorption of nutrients, which is one of the main functions of the small intestine.
The villi on the inner surface.

Vili are present to increase the surface area of the small intestine. This allows more digestion to happen in the small intestine.
Small intestine which has villi sticking out then has mircovilli causing the small intestine to have a surface area of a tennis court
