Oxygen-rich blood bound for the body tissues leaves the heart through the aorta, the major blood vessel emerging from the heart. It branches out to the arteries, which in turn branch into smaller vessels called arterioles (little arteries). These then branch into tiny, thin-walled capillaries. Blood travels slowly as the red blood cells squeeze through tiny capillaries. The radius of the aorta is approximately 9.8 mm and the speed of the blood there is 30 cm/s. A typical capillary has...

The cross-sectional area of a certain person's aorta (the major blood vessel emerging from the heart) is 3.0 cm2, and the speed of the blood through it is 35 cm/s. A typical capillary has a cross-sectional area of 2.7 x 10-7 cm2 and a flow speed of 0.058 cm/s. How many capillaries does the person have?

The approximate inside diameter of the aorta is 0.53 cm; that of a capillary is 11 μm. The approximate average blood flow speed is 1.0 m/s in the aorta and 1.0 cm/s in the capillaries. If all the blood in the aorta eventually flows through the capillaries, estimate the number of capillaries in the circulatory system.

A liquid (ρ = 1.65 g/cm3) flows through a horizontal pipe of varying cross section as in the figure below. In the first section, the cross-sectional area is 10.0 cm2, the flow speed is 246 cm/s, and the pressure is 1.20 105 Pa. In the second section, the cross-sectional area is 4.50 cm2. (a) Calculate the smaller section's flow speed. m/s (b) Calculate the smaller section's pressure. Pa

The large blood vessel leading from the human heart, the aorta, has an inside diameter of 1.0 cm and a length of 40 cm. The flowing blood (SG = 1.06) has a viscosity of 3.5 CP and an average velocity of 60 cm/s. Find the pressure drop across the aorta, if it is (a) horizontal, (b) vertical with upward flow, and (c) vertical with downward flow.

The heart pumps blood into the aorta at a rate of 4 L/min. Calculate the average speed of blood if the aorta’s diameter is 2 cm. The aorta branches many times until the blood finally reaches the smallest branch: the capillaries. Each capillary has an average diameter of 6 μm and a length of 1 mm, and the blood slows down to 0.5 mm/s. Calculate the number of capillaries in the body.
