arteriolar
Tiny vessel descriptor
Arteriolar describes something relating to or affecting arterioles—the smallest branches of arteries that deliver blood to capillaries.
The term appears in medical and physiological contexts: arteriolar resistance, arteriolar dilation.
These tiny vessels play a crucial role in regulating blood pressure and flow to tissues.
