What happens to meat in the mouth, stomach, and small intestine of a person?

1) food is mechanically processed in the oral cavity; a food lump is formed;
2) in the stomach, the breakdown of meat proteins begins under the action of enzymes of gastric juice and hydrochloric acid;
3) in the small intestine, protein is cleaved to amino acids by the action of digestive juice enzymes (trypsin and chymotrypsin) of the pancreas and their absorption into the blood.
