Question

what kind of tubeptubepresent in oesophagus

Answer 1

The esophagus (American English) or oesophagus (British English) (/ɪˈsɒfəɡəs/), commonly known as the food pipe or gullet, is an organ in vertebrates through which food passes, aided by peristaltic contractions, from the pharynx to the stomach. The esophagus is a fibromuscular tube, about 25 centimetres long in adults, which travels behind the trachea and heart, passes through the diaphragm and empties into the uppermost region of the stomach. During swallowing, the epiglottis tilts backwards to prevent food from going down the larynx and lungs. The word esophagus is the Greek word οἰσοφάγος oisophagos, meaning "gullet".
