PATHOLOGY

Detailed explanation-1: -Mechanical digestion in the oral cavity consists of grinding of food into smaller pieces by the teeth, a process called mastication.

Detailed explanation-2: -Mechanical Digestion The large pieces of food that are ingested have to be broken into smaller particles that can be acted upon by various enzymes. This is mechanical digestion, which begins in the mouth with chewing or mastication and continues with churning and mixing actions in the stomach.

Detailed explanation-3: -Within the mouth, the teeth and tongue begin mechanical digestion. Other accessory organs add secretions (enzymes) that catabolize food into nutrients. Accessory organs include salivary glands, the liver, the pancreas, and the gallbladder.

Detailed explanation-4: -The food is digested in the small intestine. It’s dissolved by the juices from the pancreas, liver, and intestine. The contents of the intestine are mixed and pushed forward to allow further digestion. Last, the digested nutrients are absorbed through the intestinal walls.
