Velocity of Blood Flow

Blood flow is a pulse wave that moves out from the aorta and through the arterial branches, then is reflected back to the heart.

Local Regulation of Blood Flow

Blood flow is regulated locally in the arterioles and capillaries using smooth muscle contraction, hormones, oxygen, and changes in pH.
