The convergence point of blood vessels, crucial for forming collateral channels to maintain blood flow despite vessel compromise. Collateral Channel
Alternative pathways for blood to reach its destination, vital when a primary vessel is blocked or damaged. Arterial Anastomosis
Convergence of arteries, often found near joints and vital organs, providing alternative blood pathways. Venous Anastomosis
Convergence of veins, more common than arterial, offering extensive collateral circulation. Arteriovenous Anastomosis
Direct connections between arteries and veins, bypassing capillaries, crucial for blood rerouting. End Blood Vessel
Non-anastomosing vessel with poor collateral circulation, making tissue death likely if obstructed. Capillary
Smallest blood vessels where exchange of substances occurs, often bypassed in arteriovenous anastomoses. Vascular Shunt
A type of arteriovenous anastomosis in mesenteries, allowing blood to bypass capillaries. Precapillary Sphincter
Muscle ring controlling blood flow into capillaries, can constrict to reroute blood in arteriovenous anastomoses. Collateral Circulation
Network of collateral channels ensuring blood supply despite blockages, more extensive in veins. Blood Clot
A blockage in a blood vessel that can compromise blood flow, necessitating collateral channels. Plaque
Build-up in blood vessels that can obstruct flow, highlighting the importance of collateral channels. Flexion
Movement that can compromise blood flow in joints, necessitating arterial anastomoses. Mesenteries
Serous membranes of the digestive system, containing vascular shunts as examples of arteriovenous anastomoses. Frostbite
Condition resulting from blood rerouting away from extremities in cold, due to arteriovenous anastomoses.
