Exam 10: The Blood Vessels and Blood Pressure

What is the primary method by which materials such as O₂, CO₂, and nutrients are exchanged between the blood and surrounding tissues?

When the heart is not ejecting blood into the arterial system, the pressure in the arteries falls to zero as blood drains off into the rest of the vasculature.

The process of ultrafiltration

Histamine released in injured areas produces local arteriolar vasodilation.

Indicate what effect the change in question would have on bulk flow using the answer code below: a.increases ultrafiltration and decreases reabsorption b.decreases ultrafiltration and increases reabsorption c.increases both ultrafiltration and reabsorption d.decreases both ultrafiltration and reabsorption e.would not alter ultrafiltration and reabsorption -Escape of plasma proteins into the interstitial fluid due to capillary damage

How is salt balance tied into blood pressure control?

Indicate whether arteriolar vasoconstriction or vasodilation would occur in the tissue in question by using the following answer code: a.produces vasoconstriction b.produces vasodilation c.no change in arteriolar caliber -Application of ice to a sprained ankle

If the blood pressure is recorded as 118/76, indicate the correct value of the pressure in question by writing the appropriate letter in the blank using the following answer code: a.118 mm Hg b.42 mm Hg c.97 mm Hg d.76 mm Hg e.90 mm Hg -What is the systolic pressure?

All the fluid forced out of the capillaries is filtered through the lymphatics before being returned to the venous blood.

For the following questions, choose the appropriate letter from the answer code below to make the statement true. a.increases b.inhibits or decreases c.has no effect on -Decreased parasympathetic nerve activity ____ total peripheral resistance.

Increased sympathetic stimulation of arterioles increases peripheral resistance and blood pressure.

All the following compensate for a fall in blood pressure below normal except

Resistance

Each of the following factors promotes the function of the capillaries except

Describe the factors involved in capillary filtration and reabsorption.Include the following in your answer: blood osmotic pressure (BOP), blood hydrostatic pressure (BHP), interstitial fluid osmotic pressure (IOP), interstitial fluid hydrostatic pressure (IHP), arteriolar end, and venular end.

Use this figure to answer the corresponding questions. -Which vessels contain red blood cells? a.vessels 1, 2, and 3 b.vessels 2, 3, and 4 c.vessels 2, 3, and 5 d.vessels 2, 3, 4, and 5 e.vessels 1, 2, 3, and 5

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

For the following questions, choose the appropriate letter from the answer code below to make the statement true. a.increases b.inhibits or decreases c.has no effect on -Increased skeletal muscle activity ____ venous return.

Reactive hyperemia occurs in response to circulating epinephrine.

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