Final answer:
The term 'arteriovenous' refers to anything pertaining to both an artery and a vein, involving the network of blood vessels that carries blood throughout the body.
Step-by-step explanation:
The medical term that means pertaining to an artery and a vein is 'arteriovenous'. In the human body, blood is transported through a network of blood vessels, where arteries carry blood away from the heart and veins return blood to the heart. The transition between these two types of vessels occurs through a series of smaller blood vessels, including capillaries, which facilitate the exchange of nutrients and wastes, arterioles, which are the smaller branches of arteries, and venules, which are small vessels that carry blood to a vein. The term 'arteriovenous' is often used in the context of certain medical conditions or procedures that involve both arteries and veins, such as arteriovenous malformations or arteriovenous fistulas, where there is a direct connection between an artery and a vein.
