Consider a 4-mm diameter blood vessel and two 2-mm diameter blood vessels. Assuming pressure, viscosity, and vessel length are constant, would the two 2-mm vessels have more, less, or the same amount of fluid flow as the 4-mm diameter blood vessel? Explain using the proper equation, showing your work and using proper units.

If the radius of a blood vessel drops to 82.0% of its original radius because of the buildup of plaque, and the body responds by increasing the pressure difference across the blood vessel by 15.0%, what will have happened to the flow rate? The flow rate will have changed to _______ % of its original value.

The branching of a blood vessel is shown in Fig. B.8. Blood at a
pressure of 18.5 kPa flows in the main vessel at 4.5 L/min.
Determine the blood pressure in each branch, assuming that blood
vessels behave as rigid tubes, the flow is frictionless, and that
the vessel lies in a horizontal plane. You may approximate blood to
have a SG of 1.06.

The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...
