1
Q

The circulatory route that runs from the digestive tract to the liver is called

A

hepatic portal circulation

2
Q

Aldosterone will

A

Promote an increase in blood Pressure

3
Q

The Pulse is

A

systolic pressure minus diastolic pressure. 

4
Q

Which of the following is likely during vigorous exercise?

A

capillaries of the active muscles will be engorged with blood.

5
Q

Peripheral Resistance

A

increases as blood viscosity increases.

6
Q

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

A

Tunica Media

7
Q

Hypovolemic Shock

A

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

8
Q

In the dynamics of blood flow through capillaries, hydrostatic pressure

A

is the same as capillary blood pressure.

9
Q

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

A

Tunica Media

10
Q

The influence of blood vessel diameter on peripheral resistance is

A

significant because as diameter decreases, resistance increases.

11
Q

The ______ vein carries nutrient-rich blood to the liver.

A

hepatic portal vein

12
Q

The ______ is squamous epithelium attached to a basement membrane.

A

Tunica Intima

13
Q

Factors that aid venous return include all except,

A

Urinary Output

14
Q

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

A

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

15
Q

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

A

The Dural Sinus Reflex

16
Q

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

A

Capillaries

17
Q

Select the correct statement about blood flow.

A

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

18
Q

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

A

Fenestrated

19
Q

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

A

Sinusoids

20
Q

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

A

anastomoses

21
Q

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

A

Baroreceptors

22
Q

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

A

Pulse Pressure

23
Q

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

A

Korotkoff

24
Q

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

A

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.

25
Q

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

A

Femoral Artery
