1How many litres of blood is usually found in the body?
- A4-6
- B6-8
- C8-10
2Which of the following statements regarding pulmonary circulation is false?
- ABlood is pumped by the left ventricle into the pulmonary arteries
- BO2 concentration in the pulmonary arteries is low
- CIn the pulmonary capillaries O2 is picked up and CO2 is offloaded
- DO2 content in the pulmonary veins is high
3Which of the following statements regarding systemic circulation is false?
- AIt carries blood from the heart to the body organs and tissues and back
- BBlood is pumped by the left ventricle into the aorta and branches
- CCO2 content of blood in the aorta is high
- DIn the tissue capillaries, O2 is off-loaded and CO2 is picked up
- EO2 content of blood in the systemic veins is low
4The vascular beds of the different tissues are arranged in series
- ATrue
- BFalse
5What are the two exceptions to the 'strictly in parallel' rule?
- Asplanchnic circulation
- Brenal system
- Cpelvic circulation
- Dpulmonary circulation
6Having vascular beds to different organs arranged “in parallel” makes sound physiological sense: the total resistance of "resistances" arranged in [blank_start]parallel[blank_end] is much lower than if arranged in [blank_start]series[blank_end]
- Aparallel
- Bseries
7Which if the following equations is correct?
- AMAP=CO x TPR
- BTPR=MAP x CO
- CCO= MAP x TPR
- DMAP= CO + TPR
8CO stands for [blank_start]cardiac output[blank_end]
- Acardiac output
9Which of the following equations is correct?
- ACO=SV x HR
- BCO = MAP x TPR
- CCO = SV x MAP
- DCO = HR x TPR
10What is the unit used to measure cardiac output?
- Aml/sec
- Bml/min
- CL/sec
- DL/min
11What is a typical value for cardiac output of an adult at rest(L/min)?
- A5-6
- B4-5
- C6-7
- D3-4
12Which of the following is a typical value for CO during severe exercise(l/min)?
- A35-42
- B22-27
- C11-18
- D28-35
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
- Aproportional
- Bconcentration
14What is Fick's principle used to determine?
- AStroke volume
- BMean arterial pressure
- Ctotal peripheral reistance
- Dcardiac output
15Which of the following are used in Fick's principle to determine CO?
- AStroke volume
- BPartial pressure of oxygen
- Cdifference in concentration of oxygen before and after it leaves the lungs
- Dthe rate that oxygen is consumed at
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
- A5
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)
- Aventricle
- Batrium
- Csystole
- Ddiastole
- Esystolic
- Fdiastolic
18During diastole pressure in the arteries falls to a minimum, this is know as [blank_start]diastolic pressure[blank_end]
- Adiastolic pressure
19Label the following with the correct figure, no need to write the % sign
- A30
- B6
- C18
- D10
- E20
- F2
- G14
- H25
- I20
- J13
- K4
- L20
- M8
- N10
20Fill in the L/min blanks in the following table, don't write the units
- A0.75
- B1
- C0.85
- D15
21Which of the following statements regarding arteries is false?
- AAt the level of the arterioles there are ~0.16x10^9 vessels
- BThere are ~5 x10^9 capillaries
- CThe radius of the aorta is ~2.5 cm
- DThe diameter of a capillary is only 8 µm
22 On average there are more blood vessels on the [blank_start]venous[blank_end] than on the [blank_start]arterial[blank_end] side
- Avenous
- Barterial
- Carterial
- Dvenous
23Fill in the percentages in the following pie chart. don't write the % sign
- A10-12
- B8-11
- C10-12
- D4-5
- E60-70
24Which of the following regarding blood flow velocity is false?
- ABlood flow doesn't change in the different parts of the CVS
- BArteries: Mean velocity 20 cm/sec
- CAorta: velocity fluctuates from 0 to very high (max 150 cm/sec)
- DBlood flow velocity varies
25Velocity of flow is [blank_start]inversely[blank_end] proportional to cross-sectional area
- Ainversely
