Exam 8: Vascular Physiology

MATCHING Indicate which type of vessel performs the function listed by using the answer code (options may be used more than once or not at all): -site of exchange of nutrients and waste products between the blood and surrounding tissues

Choose the appropriate letter from the answer code to make the statement correct. -Decreased rate of firing in afferent nerves reaching the cardiovascular control centre ____________________ the sympathetic nerve activity to the cardiovascular system.

Match the term with the correct characteristic by using the answer code: -local arteriolar mechanisms that are aimed at keeping tissue blood flow fairly constant in spite of rather wide deviations in mean arterial driving pressure

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

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

Would any sound be heard when cuff pressure was 118 mm Hg? ____________________. g. Would any sound be heard when cuff pressure was 75 mm Hg? ____________________.

Given the following parameters,what would the reabsorption pressure be? - blood capillary pressure at arteriolar end of tissue capillaries: 35 mm Hg - blood capillary pressure at venule end of tissue capillaries: 15 mm Hg - blood-colloid osmotic pressure: 22 mm Hg - interstitial-fluid hydrostatic pressure: 1 mm Hg - interstitial-fluid-colloid osmotic pressure: 0 mm Hg

Varicose veins develop mainly from the incompetent function of which following statement?

Baroreceptors are mainly found in the carotid sinus and ____________________.

A local increase in potassium increases the vasodilation of arterioles.

What is the primary reason that edema may occur with serious burns?

Which of the following is correct for the arteries?

What is the major determinant influencing resistance to blood flow?

The colloidal osmotic pressure in the blood plasma draws fluid into the capillary.

Movement of fluid from the interstitial fluid into the plasma is known as ____________________.

Indicate what effect the changes in question would have on blood flow, by using the answer code (options may be used more than once or not at all): -increasing the number of circulating red blood cells

MATCHING Indicate which type of vessel performs the function listed by using the answer code (options may be used more than once or not at all): -act as a pressure reservoir to drive blood forward throughout the vasculature during cardiac diastole
