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.

Detailed explanation-2: -Stomach. Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices.

Detailed explanation-3: -Pancreas. The pancreas secretes digestive enzymes into the duodenum that break down protein, fats and carbohydrates. The pancreas also makes insulin, passing it directly into the bloodstream. Insulin is the chief hormone in your body for metabolizing sugar.

Detailed explanation-4: -Your stomach, small intestine and pancreas all make digestive enzymes. The pancreas is really the enzyme “powerhouse” of digestion. It produces the most important digestive enzymes, which are those that break down carbohydrates, proteins and fats.

Detailed explanation-5: -The lining of the stomach produces gastric juices that contain protein-digesting enzymes. Peristaltic movements of the stomach wall mix and churn the food with the gastric juices. This action further breaks up the food particles, forming a milky fluid known as chyme.
