   2. BO2 concentration in the pulmonary arteries is low
   3. CIn the pulmonary capillaries O2 is picked up and CO2 is offloaded
   4. DO2 content in the pulmonary veins is high
3. 3Which of the following statements regarding systemic circulation is false?

   1. AIt carries blood from the heart to the body organs and tissues and back

7. 7Which if the following equations is correct?

   1. AMAP=CO x TPR
   2. BTPR=MAP x CO

   1. Acardiac output
9. 9Which of the following equations is correct?

   1. ACO=SV x HR
   2. BCO = MAP x TPR
   3. CCO = SV x MAP
   4. DCO = HR x TPR
10. 10What is the unit used to measure cardiac output?

    1. Aml/sec
    2. Bml/min
    3. CL/sec
    4. DL/min

11. 11What is a typical value for cardiac output of an adult at rest(L/min)?

    1. A5-6
    2. B4-5
    3. C6-7
    4. D3-4
12. 12Which of the following is a typical value for CO during severe exercise(l/min)?

    1. A35-42
    2. B22-27
    3. C11-18
    4. D28-35
13. 13Fick's Principle states that blood flow is [blank_start]proportional[blank_end] to the difference in [blank_start]concentration[blank_end] of a substance in the blood as it enters and leaves an organ
    

    1. Aproportional
    2. Bconcentration
14. 14What is Fick's principle used to determine?

    1. AStroke volume
    2. BMean arterial pressure
    3. Ctotal peripheral reistance
    4. Dcardiac output
15. 15Which of the following are used in Fick's principle to determine CO?

    1. AStroke volume
    2. BPartial pressure of oxygen
    3. Cdifference in concentration of oxygen before and after it leaves the lungs
    4. Dthe rate that oxygen is consumed at
16. 16Use Fick's principle and the figures in the following diagram to determine cardiac output(l/min). write only the number in the blank and not the unit

    

    1. A5
17. 17When the left [blank_start]ventricle[blank_end] contracts ([blank_start]systole[blank_end]), blood is ejected in the aorta and large arteries which are distended and pressure rises (same for the right ventricle) to a maximum ([blank_start]systolic[blank_end] pressure)
    

    1. Aventricle
    2. Batrium
    3. Csystole
    4. Ddiastole
    5. Esystolic
    6. Fdiastolic
18. 18During diastole pressure in the arteries falls to a minimum, this is know as [blank_start]diastolic pressure[blank_end]

    1. Adiastolic pressure
19. 19Label the following with the correct figure, no need to write the % sign

    

    1. A30
    2. B6
    3. C18
    4. D10
    5. E20
    6. F2
    7. G14
    8. H25
    9. I20
    10. J13
    11. K4
    12. L20
    13. M8
    14. N10
20. 20Fill in the L/min blanks in the following table, don't write the units

    

    1. A0.75
    2. B1
    3. C0.85
    4. D15
21. 21Which of the following statements regarding arteries is false?

    1. AAt the level of the arterioles there are ~0.16x10^9 vessels
    2. BThere are ~5 x10^9 capillaries
    3. CThe radius of the aorta is ~2.5 cm
    4. DThe diameter of a capillary is only 8 µm
22. 22 On average there are more blood vessels on the [blank_start]venous[blank_end] than on the [blank_start]arterial[blank_end] side

    1. Avenous
    2. Barterial
    3. Carterial
    4. Dvenous
23. 23Fill in the percentages in the following pie chart. don't write the % sign

    

    1. A10-12
    2. B8-11
    3. C10-12
    4. D4-5
    5. E60-70
24. 24Which of the following regarding blood flow velocity is false?

    1. ABlood flow doesn't change in the different parts of the CVS
    2. BArteries: Mean velocity 20 cm/sec
    3. CAorta: velocity fluctuates from 0 to very high (max 150 cm/sec)
