Solution

The correct option is D oesophagus
The process of taking in food is called ingestion. After ingestion, the food is chewed and broken down in the mouth. This food then passes through a hollow muscular tube-like structure called the oesophagus. Oesophagus shows rhythmic contraction and relaxation called peristalsis which helps to push the food (bolus) in forward direction towards the stomach.

Q. When a person puts food in his mouth, then teeth cut it into small pieces, chew and grind it. The glands A in the mouth secrete a substance B which is mixed with the food by tongue. The substance B contains an enzyme C which starts the digestion of food in the mouth. The slightly digested food from the mouth goes down a tube D. The special type of movements E in the walls of tube D push the food into stomach for further digestion. The stomach wall secretes gastric juice containing three substance F, G and H. One of the functions of F is to kill bacteria which may enter the stomach with food. The substance G protects the inside layer of stomach from the damaging effect of substance F whereas substance H is an enzyme for digestion. The partially digested food then enters into small intestine for further digestion.
