Exam 10: The Blood Vessels and Blood Pressure

The receptors for the baroreceptor reflex are located in the ____________________ and ____________________, whereas the integrating center is the ____________________ located in the ____________________. The efferent pathway for this reflex is the ____________________. The effector organs are the ____________________ and ____________________.

Indicate whether arteriolar vasoconstriction or vasodilation would occur in the tissue in question by using the following answer code: -blockage of an artery supplying a particular tissue

Accumulation of excess interstitial fluid is known as ____________________.

Blood flow is driven by ____________________.

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.

Edema, venous pooling, and a reduction in cardiac output are consequences of standing still for a long time.

The walls of the veins contain smooth muscle innervated by sympathetic nerve fibers. Sympathetic stimulation ____ venous pressure and drives ____ blood into the heart.

The following questions refer to the accompanying diagram of arteriole vasoconstriction and vasodilation. The diagram shows three state of arteriole tone. The top image labeled "A," shows normal tone. The other two panels labeled "B" and "C" show different state of arteriole tone. Match the statements below with the correct arteriole using A, B, and C. -Caused by histamine

The movements of fluid across the capillary wall depend on all of the following except

Blood flows continuously through all capillaries.

Which vessels can act as a blood reservoir by adjusting their total capacity to accommodate variations in blood volume?

Short term adjustments in blood pressure are mediated by

Which of the following properties does not pertain to the arterioles?

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: -What is the diastolic pressure?

Which statement regarding sympathetic stimulation effects on blood pressure is incorrect?

Extrinsic control of arteriolar radius

Indicate what effect the change in question would have on bulk flow using the answer code below: -loss of plasma volume due to hemorrhage

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

MATCHING Indicate which type of the vessel performs the function listed by writing the appropriate letter in the blank using the answer code below. -Portion of the circulatory system through which the velocity of blood flow is the slowest.

Total peripheral resistance is primarily dependent on ____________________.
