what does the stomach do to food
Your stomach is located at the end of your esophagus and is the terminus for swallowed food and drink. The stomach receives chewed food and continues to mechanically and chemically break it down into smaller pieces, creating more surface area for your small intestine to absorb nutrients.nother is to convert pepsinogen into pepsin. Pepsinogen is released from chief cells in your stomach wall. HCl, chemically changes pepsinogen into pepsin and is essential because pepsin doesnât function in an environment with a pH greater than 5. Pepsin begins protein digestion by breaking it down into peptide chains.
