Water soluble vitamins of dietary origin are absorbed predominantly in the small intestine, whereas those synthesized by microbes in the large intestine are absorbed there.
Beside this, what organ is most responsible for absorption?
the small intestine
where is fluid absorbed in the body?
Two third of the body water is intracellular. The extracellular fluid consists of plasma and interstitial fluids. Ingested water is absorbed mainly in the small intestine. It appears in the blood as soon as 5 minutes after ingestion.
The food is digested by stomach acid and then travels to the small intestine, where it is digested further. Nutrients are then absorbed through the wall of the small intestine. Upon absorption, the fat-soluble vitamins enter the lymph vessels before making their way into the bloodstream.
