Question 5

Peripheral Resistance

Answer 5

increases as blood viscosity increases.

Question 6

Answer 6

Tunica Media

Question 7

Hypovolemic Shock

Answer 7

shock that results from large-scale loss of blood, or after severe vomiting or diarrhea.

Question 8

In the dynamics of blood flow through capillaries, hydrostatic pressure

Answer 8

is the same as capillary blood pressure.

Question 9

Which tunic of an artery is most responsible for maintaining blood pressure and continuous blood circulation?

Answer 9

Tunica Media

Question 10

The influence of blood vessel diameter on peripheral resistance is

Answer 10

Answer 13

Urinary Output

Question 14

Select the correct statement(s) about factors that influence blood pressure.

Answer 14

Excess red cell production would cause an increase in blood pressure.

Question 15

Which of the following mechanisms do not help regulate blood pressure?

Answer 15

The Dural Sinus Reflex

Question 16

The velocity in blood flow is slowest in the _______, since the total cross-sectional area is greatest.

Answer 16

Capillaries

Question 17

Select the correct statement about blood flow.

Answer 17

Blood flow through the entire vascular system is equivalent to cardiac output

Question 18

_______ capillaries, found in the kidneys and small intestine, have pores to allow faster filtration and absorption of small molecules.

Answer 18

Fenestrated

Question 19

_______ are the most leaky type of capillaries, allowing passage of proteins and blood cells.

Answer 19

Sinusoids

Question 20

Arterial _____ provide alternate pathways for blood flow to an organ.

Answer 20

anastomoses

Question 21

The _____ in the carotid sinuses and aortic arch detect increases in blood pressure.

Answer 21

Baroreceptors

Question 22

______ , an estimation of pressure in the small arteries, is the difference between systolic and diastolic pressure.

Answer 22

Pulse Pressure

Question 23

As the sphygmomanometer cuff is deflate on the arm, ______ sounds can be heard due to turbulent flow in the brachial artery.

Answer 23

Korotkoff

Question 24

A pregnant patient notices a small, dark bulge that is becoming more apparent on her leg. What is it and what caused it?

Answer 24

Superficial veins are most likely involved because they have little support from surrounding tissues. The veins have become tortuous and dilated because of incompetent valves that allow the blood to pool, stretching the vein walls. The likely cause in this patient’s case is her pregnancies, because the enlarged uterus exerts downward pressure on groin vessels, restricting return blood flow to the heart.

Question 25

Civil war soldier shot in the thigh and bled to death. Which blood vessel was it?

Answer 25

Femoral Artery
