Exam 10: The Blood Vessels and Blood Pressure

Indicate which type of vessel performs the function listed by writing the appropriate letter in the blank using the answer code below. a.arteries b.arterioles c.capillaries d.veins e.lymphatics -Act as a pressure reservoir to drive blood forward throughout the vasculature during cardiac diastole

Receptors that detect changes in the blood pressure are located in

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 sympathetic nerve activity ____ the arteriolar radius.

Glucose is actively transported across the capillary walls.

Arteries that have lowered compliance do not have as much recoil as arteries with higher compliance.

The larger arteries assist with systemic blood flow to tissues by

Indicate which type of vessel performs the function listed by writing the appropriate letter in the blank using the answer code below. a.arteries b.arterioles c.capillaries d.veins e.lymphatics -Vessels that pick up fluid that is filtered but not reabsorbed

The major function of the arterioles is to

The pressure measured in the arteries just before the next ventricular ejection of blood is

There is a constant flow of blood through the capillaries even though the heart is forcing blood out into the arterial system only part of the time.

Cardiac contraction makes blood flow in the arterial system, but it has no influence on blood flow in the veins.

Heart and venous valves serve a similar function.They prevent a ____ flow of blood.

The microcirculation is composed of

Which of the following is not a function of the lymphatic system?

Vasoconstriction

The major site of sympathetic blood flow control (resistance changes) is at the

Each of the following local factors produces the relaxation of arteriolar smooth muscle except increased

Local control mechanisms can override sympathetic control of changes in the size of arterioles.

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 -Increased stretch of arterioles supplying a particular tissue

_______ refers to a chronic state of increased arterial pressure.
