In general, it is expected that ________.

hydrostatic pressure will drop as blood moves away from the arteriole end of the capillary bed

The velocity of blood is slowest in the capillaries and pressure of blood is lowest in the veins. Which of the following is NOT an accurate description of the benefits of slow, low pressure blood in the capillary beds?

Lower pressure in the capillary bed helps to increase pressure in the venous circulation.

Atherosclerosis causes elastic arteries to become less stretchy. How does this affect pulse pressure?

Pulse pressure is chronically increased.

Which of the following does NOT contribute to venous blood pressure? Question 1 options: a) increased abdominal pressure during breathing b) constriction of smooth muscle around veins by the sympathetic nervous system c) venous anastomoses d) skeletal muscle activity

c) venous anastomoses

capillaries
