Detailed explanation-1: -The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins. The acidic gastric juice also kills bacteria.
Detailed explanation-2: -Stomach acid allows you to digest protein, helps prevent you from developing infections and food poisoning, makes sure you’re absorbing vitamin B12 properly and signals the other digestive organs to release their juices and enzymes and muscular contractions that make digestion smooth and easy.
Detailed explanation-3: -Chemical digestion breaks large food molecules down into their chemical building blocks, which can then be absorbed through the intestinal wall and into the general circulation. Intestinal brush border enzymes and pancreatic enzymes are responsible for the majority of chemical digestion.
