In the human circulatory system, large vessels split into two (bifurcate) or more smaller vessels in progression from the aorta to the arterioles and finally the capillaries. In returning blood to the heart, the capillaries join to form venules and then finally the venae cavae. The diameter and blood velocity are given in the table below for each type of blood vessel. The viscosity of blood is 0.035. Is the flow through each of the vessels laminar, turbulent, or mixed? Diameters and Blood Velocities in the Human Circulatory

![Example: Circulatory System
In the human circulatory system, large vessels split into two (bifurcate) or more smaller
vessels in progression from the aorta to the arterioles and finally the capillaries. In
returning blood to the heart, the capillaries join to form venules and then finally the venae
cavae. The diameter and blood velocity are given in the table below for each type of blood
vessel. The viscosity of blood is 0.035. Is the flow through each of the vessels laminar,
turbulent, or mixed?
