an __________ is a small almost microscopic atery that delivers blood to capillaries.

Back 12

arteriole

Front 13

arterioles play a key role in regulating blood flow from arteries to capillaries by regulating ________.Smooth muscle in arteriole changes diameters so causesing more or less resistance(blood pressure)

Back 13

resistance
