Question

What is the other name of a food pipe?

Answer 1

The food pipe helps in passing the food to the stomach by a wave-like muscular movement called peristalsis. It is of approx 22- 25 cm long, tubular and muscular structure.

Complete answer:
The other name of the food pipe is the oesophagus. It is a tubular pipe-like structure and it does not secrete any digestive enzyme. It runs downwards through the neck behind the trachea and it passes through the diaphragm, and at last, opens in the stomach in the abdomen.
The esophagus is one of the upper parts of the gastrointestinal system. There are taste buds on its upper part. It begins at the rear of the mouth, passing downwards through the rear a part of the mediastinum, through the diaphragm, and into the stomach. In humans, the esophagus generally starts around the level of the sixth neck bone behind the cricoid cartilage of the trachea, enters the diaphragm at about the extent of the tenth dorsal vertebra, and is found to ends at the cardia of the stomach, at the extent of the eleventh dorsal vertebra. The esophagus is typically about 25 cm (10 in) long.
The upper esophagus lies at the rear of the mediastinum behind the trachea, adjoining along the tracheoesophageal stripe, and ahead of the erector spinae muscles and therefore the spinal column. The lower esophagus lies behind the guts and curves ahead of the aorta. From the bifurcation of the trachea downwards, the esophagus passes behind the proper arteria pulmonalis, left main bronchus, and left atrium of the heart. Now it passes through the diaphragm.

Note:
The oesophagus of human beings has a mucosa layer that consists of a tough stratified squamous epithelium without keratin, a smooth lamina propria, and muscularis mucosae. The epithelium of the esophagus features a relatively rapid turnover, and due to which it serves a protective function against the abrasive effects of food.
