The human circulatory system is closed - that is, the blood pumped out ofthe left ventricle of the heart into the arteries is constrained to a series ofcontinuous, branching vessels as it passes through the capillaries andthen into the veins as it returns to the heart. The blood in each of thehearts four chambers comes briefly to rest before it is ejected bycontraction of the heart muscle.The contraction of the left ventricle lasts 250 ms and the speed of bloodflow in the aorta (the large artery leaving the heart) is 0.80 m/s at the endof the contraction.

The blood flow rate through the aorta is measured to be 107.3 cm^3/s, and an adult is measured to have 5.02 L of blood. How long does it take for all of your blood to pass through the aorta? If the adult's aorta has a diamter of 2.05 cm, what is the speed of blood as it flows through the aorta?
(a) As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). If the blood speed increases by a factor of 4.00 and the total cross- sectional area of the venules is 10.0 cm2 , what is the total cross-sectional area of the capillaries feeding these venules?

L (a) The heart pumps blood into the aorta at a rate of 4 the aorta's diameter is 2.1 cm. Calculate the average speed of blood if min V blood = cm S (b) The aorta branches many times until the blood finally reaches the smallest branch: the capillaries. Each capillary has an average diameter of 6.9 μm and the blood slows down to 0.5 the number of capillaries in the body. Does this answer look reasonable? mm Calculate . S n = caps capillaries (c) For what duration of time is a red blood cell in a capillary if the average capillary length is 1 mm? t = (d) Why does the blood need to flow much slower through the capillaries than the aorta? ○ A. The capillaries are thin and might burst. ○ B. There must be sufficient time for the exchange of substances to occur across the cell membrane of the capillaries. O C. There is a smaller cross-sectional area. ○ D. None of these.

Item 12 The small capillaries in the lungs are in close contact with the alveoli. A red blood cell takes up oxygen during the 0 75 s that it squeezes through a capillary at the surface of an alveolus.
There are two carotid arteries that feed blood to the brain, one on each side of the neck and head. One patient’s carotid arteries are each 11.2 cm long and have an inside diameter of 5.2 mm. Near the middle of the left artery, however, is a 2.0-cmlong stenosis, a section of the artery with a smaller diameter of 3.4 mm. For the same blood flow rate, what is the ratio of thepressure drop along the patient’s left carotid artery to the drop along his right artery?
