Trachea Esophagus Anatomy

Knowing some basic information about the trachea esophagus anatomy is important if one wants to find out the disorders that can affect both trachea and esophagus and methods of treatment. This article is intended to provide you the basic information about the anatomy of trachea and esophagus, the similarities of these two parts of the body and also the difference between trachea and esophagus anatomy.

The anatomy of trachea and esophagus

Trachea and esophagus are the two main “pipes” of the respiratory and respectively digestive system. The main difference between trachea and esophagus anatomy is that the first is formed by a cartilaginous tissue while the latter is formed by muscular tissue. Also, the trachea divides into the left and right bronchi. A functional difference between these two parts of the digestive system is that trachea or the windpipe is the tube that transports air into the lungs and esophagus is also a tube but which transports food to the stomach.

The esophagus has three main parts: cervical, thoracic and abdominal as it extends from the lower end of the pharynx to the opening of the stomach. It has about 25 to 30 cm when one is in the erect position. The esophagus is a muscular tube that lies behind the trachea and behind the left atrium. This is the part of the digestive system that actually connects the larynx to the stomach.

The entire esophagus extends from the C5-6 vertebral interspace to the T11 vertebral level. The cervical part of the esophagus begins at the pharyngoesophageal junction and it ends at the suprasternal notch. This part of the esophagus is not longer than 5 cm. the cervical part of the esophagus is the part bordered anteriorly by the trachea and posteriorly by the vertebral column. The thoracic esophagus begins at the suprasternal notch and it ends in the diaphragmatic hiatus. It passes posterior to the trachea and the tracheal bifurcation as well as to the left main stem bronchus. The abdominal esophagus extends from the diaphragmatic hiatus to the cardia of the stomach. It is only about 1 cm long and it lies on the surface of the left lobe of the liver.

One of the most common diseases that affect the esophagus and trachea is candidiasis. Candidiasis of the esophagus trachea bronchi or lu is a fungal infection with species of Candida. Candidiasis of the esophagus trachea bronchi or lu is a systemic disease, in many cases life-threatening especially for those patients who are immunocompromised such as AIDS, cancer or transplant patients.

Trachea esophagus anatomy is therefore crucial to be known not only when surgery is performed on them, but also by every patient who suffers from the different conditions that may affect them in order to be aware of the risks and complications.
