	An '''end artery''' (~~also known as a~~ '''terminal artery''') is ~~a type of~~ [[artery]] that ~~does not anastomose with any other artery, meaning it~~ is the ~~only~~ supply of blood to a ~~certain~~ tissue ~~or organ~~. This is ~~in contrast to~~ [[~~collateral circulation~~]]~~, where multiple arteries supply the same region~~.		An '''end artery''' (or '''terminal artery''') is an [[artery]] that is the sole supply of [[oxygenated blood]] to a portion of [[tissue]]. End arteries do not have significant [[anastomosis\|anastomoses]] with other arteries. This means that if an end artery is occluded, the tissue it supplies will suffer from [[ischemia]] and may undergo [[necrosis]].

	==~~Structure~~==		== Examples ==
			Examples of end arteries include:
			* The [[central artery of the retina]], which supplies the [[retina]] of the [[eye]].
			* The [[splenic artery]], which supplies the [[spleen]].
			* The [[renal artery]], which supplies the [[kidney]].

	End arteries are typically small, with a diameter of less than 0.5 mm. They are found in various parts of the body, including the [[brain]], [[heart]], [[kidneys]], and [[lungs]]. The structure of end arteries is similar to other arteries, with three layers: the [[tunica intima]], [[tunica media]], and [[tunica adventitia]].		== Clinical significance ==
			End arteries are clinically significant because their occlusion can lead to serious consequences. For instance, occlusion of the central artery of the retina can lead to sudden [[blindness]]. Similarly, occlusion of the renal artery can result in [[renal infarction]] and loss of kidney function.
	==~~Function~~==

	~~The primary function of end~~ arteries ~~is to deliver oxygenated blood~~ to ~~specific tissues or organs~~. ~~Because they do not anastomose with other arteries~~, ~~any blockage in an end~~ artery can lead to [[~~ischemia]] or [[infarction~~]] of the ~~tissue it supplies.~~

	~~==Clinical significance==~~

'''End Artery'''

[[File:End artery.png|thumb|right|300px|Illustration of an end artery]]

An '''end artery''' (also known as a '''terminal artery''') is a type of [[artery]] that does not anastomose with any other artery, meaning it is the only supply of blood to a certain tissue or organ. This is in contrast to [[collateral circulation]], where multiple arteries supply the same region.

==Structure==

End arteries are typically small, with a diameter of less than 0.5 mm. They are found in various parts of the body, including the [[brain]], [[heart]], [[kidneys]], and [[lungs]]. The structure of end arteries is similar to other arteries, with three layers: the [[tunica intima]], [[tunica media]], and [[tunica adventitia]].

==Function==

The primary function of end arteries is to deliver oxygenated blood to specific tissues or organs. Because they do not anastomose with other arteries, any blockage in an end artery can lead to [[ischemia]] or [[infarction]] of the tissue it supplies.

==Clinical significance==

Understanding the distribution of end arteries is important in medical procedures such as [[surgery]] and [[angiography]]. For example, in [[coronary artery bypass grafting]], surgeons must be aware of the end arteries in the heart to avoid causing damage.
