NEET PG DENTAL EXAM

Detailed explanation-1: -The stomach is a muscular bag and it churns the food to help break it down mechanically as well as chemically. The food is then squeezed through a second sphincter into the first part of the small intestine, called the duodenum.

Detailed explanation-2: -The mixing of food in the human stomach occurs by peristalsis movement or wave. This wave occurs by muscular contractions that move towards the wall of the stomach.

Detailed explanation-3: -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-4: -Ridges of muscle tissue called rugae line the stomach. The stomach muscles contract periodically, churning food to enhance digestion.
