Question

1, What does a blood pressure of 120/70 tell you?

(A) At the end of ventricular diastole, the left ventricle generates 70 mmHg

(B) During atrial systole, the left ventricle generates 120 mmHg

(C) During sympathetic activation, the elastic arteries generate 120 mmHg

(D) During ventricular systole, the left ventricle generates more than 120 mmHg

(E)The aortic semilunar valve closes when aortic pressure reaches 120 mmHg

2.What is responsible for pushing fluid out across the capillary wall into the interstitial fluid?

(A) Capillary hydrostatic pressure being greater than interstitial fluid hydrostatic pressure

(B) Capillary colloid osmotic pressure being greater than interstitial fluid osmotic pressure

3. what leaves the capillary through intercellular clefts and enters the interstitial fluid?

(A)Ions, glucose, water

(B)Plasma proteins

(C)Both plasma proteins and ions, glucose, water

4. what creates the colloid osmotic pressure of the capillary?

(A) Blood pressue (hydrostatic pressure)

(B) Ions

(C) Plasma proteins

5. What happens if capillary colloid osmotic pressure is greater than capillary hydrostatic pressure? (Imagine interstitial hydrostatic pressure and interstitial osmotic pressure are both 0 mmHg.)

(A)More fluid would be pushed out of the capillary into the interstitial fluid than would be pulled in from the interstitial fluid into the capillary.

(B)More fluid would be pulled into the capillary from the interstitial fluid than would be pushed out from the capillary plasma to the interstitial fluid.

(C)No fluid would cross the capillary wall.

6. in the capillary, is all the fluid that is pushed into the interstitial space from the arterial end reabsorbed at the venous end? If not, where does it go?

(A) Yes, it all goes back into the venous end of the capillary.

(B) No, the extra fluid is drained away by the lymph vessels.

(C) No, the extra fluid collects in the tissue.

7. Which of the following will cause fluid to collect in the interstitial space (create tissue edema)?

(A) Permeability of the lymphatic capillaries decreases

(B) Increased production of albumin by the liver

(C) Permeability of the systemic capillaries decreases at the arterial end

(D) Blood pressure decreases at the arterial end

8. What happens in an otherwise normal individual if their liver cannot produce albumin?

(A)The blood would lose fluid to the tissues and the tissues would become swollen (edema)

(B)The blood would gain fluid from the tissues and the tissues would become dehydrated

9. How are total cross-sectional of vessels and velocity of blood flow related?

(A) As total cross-sectional area of vessels increases, velocity of blood flow increases

(B) As total cross-sectional area of vessels increases, velocity of blood flow decreases
