Question

explain the process of digestion in stomach

Answer 1

in stomach in stomach food breaks down into still smaller pieces it is mixed with the mucus secreted by the walls of stomach and forms of semisolid paste the wall of the stomach has gastric glands which secrete is gastric juice this gastric juice contains mucus hydrochloric acid and a prestigious or protein digesting enzymes pepsin hydrochloric acid makes the gastric juice acidic in nature and hydrochloric acid makes the medium of gastric juice acidic so that the enzymes pepsin can digest the food properly pepsin can work only in acidic medium if acidic pH is not provided the pepsin remains in active and it kills any bacteria which may enter into the stomach with food and mucus form a protective lining on the inner wall of stomach it means it protect the wall of stomach from the follows effect of hydrochloric acid and prosteolytic nature of pepsin the wall of stomach is also made of protein but it is not digested by pepsin because pepsin is secreted in an inactive form it becomes active in the presence of HCL and HCL is secreted when there is food in the stomach when there is no food there is no situation of pepsin and secondly there is a protective coating of mucus over stomach wall mucus liberates the food and gives it Semi solid texture and pepsin acts on protein and convert them convert them into simpler peptide molecules stomach store the food for two three hours later on the sphincter at the bottom of the stomach opens and let be partly digest food into small intestine

Answer 2

Partial digestion of the food takes place here. The churning action of the stomachmuscles physically breaks down the food. The stomach releases acids and enzymes for the chemical breakdown of food. The enzyme pepsin is responsible for protein breakdown.
