ANATOMY

Detailed explanation-1: -The stomach muscles churn and mix the food with digestive juices that have acids and enzymes. These juices help break up food into much smaller pieces. By the time food is ready to leave the stomach, it has been turned into a thick liquid called chyme (kime).

Detailed explanation-2: -Gastric juice is made up of digestive enzymes, hydrochloric acid and other substances that are important for absorbing nutrients – about 3 to 4 liters of gastric juice are produced per day. The hydrochloric acid in the gastric juice breaks down the food and the digestive enzymes split up the proteins.

Detailed explanation-3: -Gastric juice is a unique combination of hydrochloric acid (HCl), lipase, and pepsin. Its main function is to inactivate swallowed microorganisms, thereby inhibiting infectious agents from reaching the intestine.

Detailed explanation-4: -Digestive juices help in digestion by breaking down the food items into simple nutrients. These nutrients are then used by body for different functions.

Detailed explanation-5: -The abomasum is the only stomach compartment with glandular mucosa that can secrete digestive juices, including hydrochloric acid, pepsin, and rennin.
