食道

食道(或食管)是一个脊椎动物器官的肌肉管通过食物从胃咽。在吞咽,通过咽食物从口腔到食道和胃通过蠕动。这个词食道来源于拉丁语吗œsophagus,它源于希腊语oisophagos,点燃。“入学吃。”In humans the esophagus is continuous with the laryngeal part of the pharynx at the level of the C6 vertebra. The esophagus passes through posterior mediastinum in thorax and enters abdomen through a hole in the diaphragm at the level of the tenth thoracic vertebrae (T10). It is usually about 25–30 cm long depending on individual height. It is divided into cervical, thoracic and abdominal parts. Due to the inferior pharyngeal constrictor muscle, the entry to the esophagus opens only when swallowing or vomiting.
