Which of these statements does NOT apply to blood pressure

Which of these factors is the most important in matching the blood flow through a specific tissue with the metabolic needs of that tissue

Decreased sympathetic nerve activity _____ the arteriolar radius.

Increased sympathetic stimulation causes generalized vasoconstriction.

The primary mechanism for exchange of individual solutes across the capillary wall is ____________________.

Match the effects, labelled a. through d., with the events in question. (Options may be used more than once or not at all.) -increased vasomotor centre activity

Given the following parameters, what would the reabsorption pressure be Blood capillary pressure at arteriolar end of tissue capillaries = 35 mmHg Blood capillary pressure at venule end of tissue capillaries = 15 mmHg Plasma-colloid osmotic pressure = 22 mmHg Interstitial fluid hydrostatic pressure = 1 mmHg Interstitial fluid-colloid osmotic pressure = 0 mmHg

Which of these statements describes vasoconstriction

A major function of the arteries is to serve as a blood reservoir.

Accumulation of excess interstitial fluid is known as ______________________.

Match the effects, labelled a. through c., with the change(s). (Options may be used more than once or not at all.) -increasing the number of circulating red blood cells

The two hormones involved primarily in fluid balance and that are also potent vasoconstrictors are ____________________ and ____________________.

The flow rate of blood is the same in all segments of the vascular tree, but the velocity of blood flow is slower in the capillaries than in other segments of the vascular tree.

Match the effects, labelled a. through e., that the changes in question would have on bulk flow. (Options may be used more than once or not at all.) -loss of plasma protein into the urine due to kidney disease
