Lecture 9: Cardiac Pressure-Volume Cycle Flashcards
1
Q
what is the circle of willis
A
- arteries on brain’s inferior surface organised into a circle
- offers redundancy of blood supply
2
Q
which enzymes do the kidney produce
A
- ACE and renin
- control blood volume
- responding to renal blood pressure
3
Q
what effect does adrenergic input have on skeletal muscles
A
vasodilation
4
Q
what is the skin’s reaction to trauma
A
- red reaction
- flare
- wheal
5
Q
what are the stages in the cardiac pressure-volume loop
A
- ventricular filling
- isovolumic ventricular contraction
- ejection
- isovolumic ventricular relaxation
6
Q
when is a systolic murmur heard
A
- when fluid leaves the ventricle
- AV regurgitation or semilunar stenosis
7
Q
when is a diastolic murmur heard
A
- when fluid enters the ventricle
- AV stenosis or semilunar regurgitation
8
Q
where do we see pacemaker potential
A
- SA node
- AV node
- conduction system only
