Blood flow is the flow of blood in the cardiovascular system. The discovery that blood flows is attributed to William Harvey.

Mathematically, blood flow is described by Darcy's law (which can be viewed as the fluid equivalent of Ohm's law) and approximately by Hagen-Poiseuille's law. Blood is a heterogeneous medium consisting mainly of plasma and a suspension of red blood cells. White cells, or leukocytes, and platelets while present in smaller concentrations, play an important role in biochemical processes, such as immune response, inflammation, and coagulation. Red cells tend to coagulate when the flow shear rates are low, while increasing shear rates break these formations apart, thus reducing blood viscosity.This results in two non-Newtonian blood properties, shear thinning and yield stress. In healthy large arteries blood can be successfully approximated as a homogeneous, Newtonian fluid since the vessel size is much greater than the size of particles and shear rates are sufficiently high that particle interactions may have a negligible effect on the flow. In smaller vessels, however, non-Newtonian blood behavior should be taken into account. The flow in healthy vessels is generally laminar, however in diseased (e.g. atherosclerotic) arteries the flow may be transitional or turbulent. The first equation below is Darcy's law, the second is the Hagen-Poiseuille law:
