Q

What is the circulation of the pulmonary circuit?

A

Q

What is the circulation of the systemic circuit?

A

Circulation of oxygenated blood to the body through the aorta and deoxygenated blood back to the heart through the vena cava.

Q

what is a cardiac cycle?

A

A heart beat

17
Q

What are the two phases of a cardiac cycle?

A
  1. diastole

2. systole

18
Q

What is the diastole phase?

A

relaxation of heart where chambers fill with blood

19
Q

What is the systolic phase?

A

contraction of the heart where blood is forcibly ejected

20
Q

How does the cardiac cycle go?

A
  1. atrial diastole
  2. ventricular diastole
  3. atrial systole
  4. ventricular systole
21
Q

Describe the diastole phase:

A

atria and ventricles relax theerfore low pressure in heart
blood passively moves from atria to ventricles
AV valves are open to allow blood to flow
SV valves are closed

22
Q

Describe the systole phase:

A

atria contract forcing blood into ventricles
high pressure in heart
AV valves close
SA node fires faster
SV valves open up
Blood pushed out of heart to large arteries leading to the body

23
Q

definition of heart rate:

A

number of times the heart beats in a minute

24
Q

definition of stroke volume:

A

amount of blood ejected from left ventricle in one heart beat

25
Q

definition of cardiac output

A

amount of blood ejected from left ventricle in one minute

26
Q

What is HR, SV and Q at rest?

A 
HR = 70bpm
SV = 70ml
Q = 5L
27
Q

What is HR, SV and Q for trained person at rest?

A 
HR = 50bpm
SV = 100ml
Q = 5L
28
Q

What id bradycardia?

A

a resting heart rate under 60bpm

29
Q

how to calculate max heart rate:

A

220-age = max HR

30
Q

Karvonen’s principle:

A

220 - age = Max HR
Max HR - resting HR = HR reserve
(HR reserve x training %) + resting HR

31
Q

What is venous return

A

The volume of blood returning back to the heart

32
Q

What is HR, SV and Q for an untrained person at sub max exercise?

A 
HR = 100bpm
SV = 100ml
Q = 10L
33
Q

What is HR, SV and Q for an untrained person at max exercise?

A 
HR = 220 - age
SV = 100 
Q = 20 L
34
Q

What is HR, SV and Q for a trained person at sub max exercise?

A 
HR = 100bpm
SV = 200ml
Q = 15L
35
Q

What is HR, SV and Q for a trained person at max exercise?

A 
HR = 220-age
SV = 200ml
Q = 30L
