Exam 8: Vascular Physiology

Measurement of arterial pressure using a sphygmomanometer is possible because turbulent blood flow that occurs as arterial pressure overcomes a partially occluded artery and can be heard by a stethoscope placed just over the artery.

By using the answer code (options may be used more than once or not at all), indicate whether the following would -facultative Na⁺ reabsorption

The capillary vessel walls are more permeable than the lymphatic vessel walls.

Which of the following will NOT cause an increase in blood pressure?

By using the answer code (options may be used more than once or not at all), indicate whether the following would -stress

Edema refers to excess interstitial fluid.

Choose the appropriate letter from the answer code to make the statement correct. -Increased arteriolar radius ____________________ the total peripheral resistance.

Heart and venous valves serve a similar function.What type of flow do they prevent?

If the pulse pressure is 44 mm Hg and the diastolic pressure is 68 mm Hg,what is the systolic pressure?

Arteries that have lowered compliance are not as elastic.

Which of the following alterations could lead to edema?

How does the vasomotor centre respond to rising H⁺/CO₂?

Total peripheral resistance is primarily dependent on ____________________.

What may NOT cause hypertension?

The extra fluid filtered but not reabsorbed at the capillary level is picked up by the lymphatics.

The mean arterial pressure is a simple average of the systolic and diastolic pressures.

Indicate whether arteriolar vasoconstriction or vasodilation would occur in the tissue in question by using the answer code (options may be used more than once or not at all): -decreased O₂ in skeletal muscle

Histamine released in injured areas produces local arteriolar vasodilation.

Baroreceptors are most sensitive to changes in which of the following?

If the arterial blood pressure is recorded at 132/84,what is the mean arterial pressure?
