This is a crucial aspect of the body&#039;s [[circulatory system]], as it ensures that tissues and organs continue to receive oxygen and nutrients even when a primary artery is obstructed.<br /> <br /> ==Structure==<br /> <br /> Collateral arteries are small, normally closed arteries that connect two larger arteries. They are typically not involved in regular blood flow, but can open and expand when necessary to bypass a blockage. This process is known as [[collateral circulation]].<br /> <br /> ==Function==<br /> <br /> The primary function of collateral arteries is to maintain blood flow to tissues and organs when a main artery is blocked. This can occur in response to a variety of conditions, including [[atherosclerosis]], [[thrombosis]], and [[embolism]]. Collateral circulation can also be important during [[exercise]], when increased blood flow is required.<br /> <br /> ==Clinical significance==<br /> <br /> The presence and functionality of collateral arteries can significantly impact the outcome of conditions such as [[coronary artery disease]] and [[stroke]]. In some cases, collateral circulation can prevent tissue death and reduce the severity of these conditions. However, the extent and effectiveness of collateral circulation can vary greatly between individuals.<br /> <br /> ==See also==<br /> <br /> * [[Artery]]<br /> * [[Blood vessel]]<br /> * [[Circulatory system]]<br /> * [[Coronary artery disease]]<br /> * [[Stroke]]<br /> <br /> ==References==<br /> <br /> &lt;references /&gt;<br /> <br /> [[Category:Arteries]]<br /> [[Category:Cardiovascular system]]<br /> [[Category:Anatomy]]<br /> <br /> {{anatomy-stub}}</div>
