Blood supply Arteries Now that we’ve seen the main parts and junctions of the esophagus, it’s time to look at its neurovasculature. We’ll firstly begin by looking at the arterial blood supply. The arteries supplying the esophagus are generally named ‘esophageal arteries’. The only difference between them is given by their origins ...
The cervical esophagus and UES are supplied with blood via branches of the inferior thyroid artery. The thoracic esophagus is supplied by the aortic esophageal arteries which are at the terminal branches of the bronchial arteries.
The thoracic part of the oesophagus receives its arterial supply from the branches of the thoracic aorta and the inferior thyroid artery (a branch of the thyrocervical trunk). Venous drainage into the systemic circulation occurs via branches of the azygous veins and the inferior thyroid vein.
This large vein will be carrying blood or venous blood from the lower half of your body towards the heart. Now, the inferior vena cava is formed by the joining of two veins – the left and right common iliac veins – and anastomosis with the azygos vein system which we will talk about later.
A continuous intensive network arteries located in the submucosa connects all the extramural vessels, which results in the copious blood supply to the esophagus. Blood from the proximal and distal esophagus is drained via the azygous system, which in turn drains directly into the superior vena cava.
Venous blood from the esophagus drains into a submucosal plexus. From this plexus, blood drains to the periesophageal venous plexus. Esophageal veins arise from this plexus and drain in a...
The arterial supply to the esophagus comes from the esophageal branches that arise from multiple arteries, including the inferior thyroid arteries, thoracic aorta, bronchial arteries, left gastric artery, and left inferior phrenic artery.

Quick Facts. Location: Extends from the pharynx to the stomach, anterior to the vertebral bodies of the vertebral column. Arterial Supply: Inferior thyroid artery, esophageal branches of descending thoracic aorta, branch of right bronchial artery, left gastric, and left inferior phrenic arteries.
The esophagus is a muscular channel that carries food from the pharynx to the stomach. It starts with the upper esophageal sphincter, formed in part by the cricopharyngeus muscle, and ends with the lower esophageal sphincter, surrounded by the crural diaphragm. When food enters the mouth, it mixes with saliva.
The majority of the arterial flow is supplied to the thoracic portion of the esophagus via the bronchial arteries and the four to six esophageal branches of the aorta. This blood supply is supplemented by descending branches from the inferior thyroid arteries and intercostal arteries and ascending branches of the paired inferior phrenic arteries.
