The major site of nutrient absorption is the small intestine.
The small intestine, or the duodenum, is where most absorption of nutrients occur.
The small intestine is to nutrient absorption as the blood is to nutrient distribution.

In the average person, approximately 80-90% of alcohol is absorbed through the small intestine. The remaining absorption occurs in the stomach and other parts of the gastrointestinal tract. The rapid absorption in the small intestine is due to its large surface area and the presence of specialized transport mechanisms. This makes the small intestine a key site for alcohol absorption into the bloodstream.
The small intestine, specifically the jejunum is where most of the absorption occur.
90% of the digestion and absorption of food occurs in the small intestine.
The small intestine has small tiny projections called "villi". These projections increase the surface area for absorption. The large intestine however lacks these structures.
Most absorption takes places in the small intestine. More specifically, it is the jejunum portion of the small intestine that does the bulk of the absorption.

Absorption of amino acids and simple sugars primarily occurs in the small intestine. The inner surface of the small intestine is lined with villi and microvilli that increase the surface area for absorption. Nutrients are absorbed into the bloodstream through the villi and then transported to cells throughout the body for energy and growth.
