GENERAL HISTOLOGY

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: -The chemical digestion of proteins happens due to acidic digestive fluids that are secreted by the gastric glands, called gastric juices.

Detailed explanation-3: -The stomach secretes gastric juice that has a pH between 1.5 and 2.5. This highly acidic environment is required for the chemical breakdown of food and the extraction of nutrients. The stomach also contains smooth muscle which helps in mechanical digestion known as the churning of food.

Detailed explanation-4: -Chewing and the churning motions in your stomach are the main forces involved in this process. Chemical digestion. This is the process where complex molecules like proteins, fats, and carbohydrates are broken down into smaller pieces that your body can use. It requires special proteins called enzymes.

Detailed explanation-5: -Gastric juice renders food particles soluble, initiates digestion (particularly of proteins), and converts the gastric contents to a semiliquid mass called chyme, thus preparing it for further digestion in the small intestine.
