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.

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 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 human circulatory system delivers oxygenated blood from the lungs throughout the human body to enable the transport to and from body cells of oxygen, carbon dioxide, nutrients, hormones and blood cells. A variety of sizes of arteries and veins are required to ful?l this need. (a) A typical heartbeat pumps 75 mL of blood over a time span of 0.36 seconds into the aorta. If under this pressure the aorta expands to a diameter of 4.2 mm, what is...

The heart requires a continuous flow of blood maintain normal function. The average length of the mid left anterior descending coronary artery is 11 cm and the average diameter is 4.6 mm. The necessary blood flow through this artery is 127 mL/min. Calculate the decrease in pressure along this artery. b. If plaque deposits reduce the diameter of this artery to 2.6 mm, what would be the new decrease in pressure?
