Absorption is the process by which the end products of digestion pass through the intestinal epithelium and enter the blood stream. Attempts have been made to explain the mechanism of absorption on the basis of known physico-chemical principles. The following factors are believed to be involved in the process: i. Diffusion: This depends upon the relative concentration of the substances [...]
In this article we will discuss about the absorption of water and salts in human body. Absorption of Water: Very little water is absorbed from the stomach. Water introduced into the stomach almost immediately passes into the small intestine which is the chief seat of water absorption. The intestinal contents near the ileocecal valve contain the same proportion of water [...]
The recent knowledge regarding the mechanism of fat absorption in human body has been briefly discussed below: Most dietary fat of either vegetable or animal origin comprises of triglycerides in which glycerol is combined in low-energy ester linkages with three fatty acids and the fatty acids are of even number of carbon atoms. Fatty acids are both saturated and unsaturated [...]
