Detailed explanation-1: -The small intestine extends from the pyloric sphincter to the ileocecal valve, where it empties into the large intestine. The small intestine finishes the process of digestion, absorbs the nutrients, and passes the residue on to the large intestine.
Detailed explanation-2: -The food that you eat passes from your mouth through your esophagus to your stomach. It then goes from your stomach to your small intestine. These organs break down food into bits that your body absorbs and uses for energy. By the time the food you eat gets to your large intestine, most of the digestion is done.
Detailed explanation-3: -Absorption of water occurs by osmosis. Water diffuses in response to an osmotic gradient established by the absorption of electrolytes. Sodium is actively absorbed in the colon by sodium channels. Potassium is either absorbed or secreted depending on the concentration in the lumen.
