Which part of the human digestive system absorbs most of the nutrients ?
Small intestine
Digestion of food is completed in the small intestine, where enzymes from the pancreas, liver (bile) and intestinal wall break food into simple absorbable units.
The inner wall of the small intestine has millions of finger-like villi and microvilli that give a very large surface area, and through them glucose, amino acids, fatty acids, vitamins and minerals pass into blood and lymph.
The stomach absorbs only small amounts of water, alcohol and some drugs, the oesophagus only carries food, and the large intestine mainly absorbs water and salts.
Hence, Small intestine.
