Q

What would happen in the body if one side of the heart pumped more blood than the other?

A

Blood would accumulate in the structures being supplied by the side of the heart which was pumping more blood

(i.e. if right side pumped more, blood would accumulate in lungs)

17
Q

Venules collect blood from

A

capillaries

18
Q

What side of the heart is responsible for mean arterial pressure?

A

Left

19
Q

What artery is classed as an elastic artery?

A

The aorta

20
Q

Structure of a blood vessel always relates to its

A

funtion

21
Q

What effect does the aorta have on pressure variations?

A

The aorta reduces pressure variations

22
Q

What kind of wall do arteries (other than the aorta) have?

A

Strong muscular/non-elastic

23
Q

Do arteries have a narrow or wide lumen?

A

Wide

24
Q

What is the main function of arteries (other than the aorta)?

A

Provide a low resistance conduit for blood

25
Q

What vessels allow the regional redirection of blood?

A

Arterioles

26
Q

What are the main exchange vessels?

A

Capillaries

27
Q

What vessels are known as capacitance vessels?

A

Veins and venules

28
Q

What is the main structural difference between arteries and arterioles?

A

Arteries have a much narrower lumen

29
Q

Give two functions of capacitance vessels

A
  • low resistance conduit

- blood reservoir

30
Q

What is the function of the interventricular septum?

A

To separate the right and left ventricles

31
Q

What is the myocardium?

A

The muscular wall of the heart

32
Q

What chambers of the heart receive blood?

A

Atria

33
Q

Blood is pumped out of the right ventricle through what structure?

A

The pulmonary trunk

34
Q

What do valves prevent?

A

Back-flow of blood

35
Q

On what side of the heart is the mitral valve?

A

Left

36
Q

On what side of the heart is the tricuspid valve?

A

Right

37
Q

What structures connect the papillary muscles to the mitral/tricuspid valves?

A

Chordae tendinae

38
Q

If the papillary muscle was not present, what might happen to the valves?

A

Valves would invert
