食管与气管

食道和气管有很大的区别。如果你对身体的这两个重要部位有任何困惑，请看看我们下面描述的区别！

• 功能第一个也是最明显的区别是气管是呼吸系统的一部分，而食道是消化系统的一部分。因为它们属于不同的系统，所以它们执行不同的功能！
• Structure-The trachea, commonly called a windpipe, is a strong and wide tube that helps in transporting air to the bronchi. It is the most important part of animals that breathe in through their lungs. Since it supplies the body with oxygen, it is very important for the trachea to remain open at all times. Some allergic reacti*** may cause an inflammation of the trachea. The patient faces imminent death if he does not receive prompt medical treatment. The esophagus is **aller and more flexible in structure (naturally, look at the amount of food it needs to transport!). It is the link between your mouth and the stomach. Muscular movements of the esophagus result in the passage of food from the mouth to the stomach cavity. The esophagus and the trachea are located at roughly the same place. They are separated by the epiglottis-a tiny flap that protects the trachea when you swallow something!
• 气管的长度和位置由许多软骨半圆形环组成。这些可以防止气管塌陷。它大约有9到15厘米长。它位于食道前面。食道是一个肌肉管，大约10英寸长。
• Parts- Another difference between the two relate to their structure. The trachea has both thoracic and cervical parts. It extends from one end of the larynx. The esophagus, on the other hand has three parts-the cervical, abdominal and the thoracic parts. It extends from the lower side of the pharynx to the cardiac opening to the stomach. It has a number of c***tricti*** right at the place it originates. Food particles can lodge themselves in these areas. However, the structure of the esophagus is amazingly flexible-it can swallow almost anything!
• Blood supply- Another important difference between the two relate to their blood supply. The esophagus is supplied by arteries in the neck, thorax and the abdomen.

  However, the trachea is mainly supplied by the inferior thyroid arteries.

Summary:1. The 气管是呼吸系统的一部分，而食道是消化系统的一部分。气管输送空气，食管输送食物。气管较长，食管较灵活。气管有两部分，食道有三部分。气管由甲状腺下动脉供血，而食道则由体内不同部位的不同动脉供血。
