Esophageal Arteries

	Esophageal Arteries Esophageal (Oesophageal in British English) arteries are a group of arteries from disparate sources supplying the esophagus. The blood supply to the esophagus can roughly be divided into thirds, with anastamoses between each area of supply. More specifically, it can refer to: * Esophageal branches of inferior thyroid artery (top third) * Esophageal branches of thoracic part of aorta The esophageal arteries four or five in number, arise from the front of the aorta, and pass obliquely downward to the esophagus, forming a chain of anastomoses along that tube, anastomosing with the esophageal branches of the inferior thyroid arte ... (middle third) * Esophageal branches of left gastric artery (bottom third) Arteries {{circulatory-stub ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Esophageal Veins The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein, posterior intercostal vein and bronchial veins. In the abdomen, some drain to the left gastric vein The left gastric vein (or coronary vein) is a vein that derives from tributaries draining the lesser curvature of the stomach. Structure The left gastric vein runs from right to left along the lesser curvature of the stomach. It passes to the ... which drains into the portal vein.

picture info	Esophagus The esophagus ( American English) or oesophagus (British English; both ), non-technically known also 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 long in adults, that 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 ''oesophagus'' is from Ancient Greek οἰσοφάγος (oisophágos), from οἴσω (oísō), future form of φέρω (phérō, “I carry”) + ἔφαγον (éphagon, “I ate”). The wall of the esophagus from the lumen outwards consists of mucosa, submucosa (connective tissue), layers of muscle fibers between layers of fibrous tissue, and an outer layer of connective tissue. The mucosa is a stratified squamous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Arteries An artery (plural arteries) () is a blood vessel in humans and most animals that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.). Most arteries carry oxygenated blood; the two exceptions are the pulmonary and the umbilical arteries, which carry deoxygenated blood to the organs that oxygenate it (lungs and placenta, respectively). The effective arterial blood volume is that extracellular fluid which fills the arterial system. The arteries are part of the circulatory system, that is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of optimum blood pH, and the circulation of proteins and cells of the immune system. Arteries contrast with veins, which carry blood back towards the heart. Structure The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with a micro ...

	Esophageal Branches Of Inferior Thyroid Artery The inferior thyroid artery is an artery in the neck. It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle. It then turns medially behind the carotid sheath and its contents, and also behind the sympathetic trunk, the middle cervical ganglion resting upon the vessel. Reaching the lower border of the thyroid gland it divides into two branches, which supply the postero-inferior parts of the gland, and anastomose with the superior thyroid artery, and with the corresponding artery of the opposite side. Structure The branches of the inferior thyroid artery are the inferior laryngeal, the oesophageal, the tracheal, the ascending cervical and the pharyngeal arteries. The inferior laryngeal artery climbs the trachea to the back part of the larynx under cover of the inferior pharyngeal constrictor muscle. It is accompanied by the recurrent nerve, and supplies the muscles and mucous membrane of this part, anastomosing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Esophageal Branches Of Thoracic Part Of Aorta The esophageal arteries four or five in number, arise from the front of the aorta, and pass obliquely downward to the esophagus, forming a chain of anastomoses along that tube, anastomosing with the esophageal branches of the inferior thyroid arteries above, and with ascending branches from the left inferior phrenic and left gastric arteries below. These arteries supply the middle third of the esophagus.
