Total questions: 10
Worksheet time: 7mins
The AV (atrioventricular valves) separate the
atria from the ventricles
atria from the lungs
lungs from the heart
The tricuspid valve divides
(a)
What is the semilunar valves
3 valves that are left sided aortic
2 valves that have 3 leafs and are the right-sided pulmonic valve or the left-sided aortic
2 valves that have 2 cups and are right-sided pulmonic valve
What is SV stroke volume?
(a)
What does the SV (stroke volume) rely on
preload (amount of blood returning to the heart)
afterload (pressure the heart pumps against)
contractibility (strength of the muscle contraction)
amount of blood in heart
What is the cardiac cycle
period from 1 contraction to the next contraction
period beginning of 1 contraction through the phase just before the start of the next contraction
phase of relaxation
Systole in the cardiac cycle is the period
ventricles and atria are relaxing
ventricles and atria are actively contracting
the atria is contracting
the ventricles are contracting
The Diastole of the cardiac cycle is the period when the heart
pushes blood through the system
contracts (and fills chamber with blood)
relaxes (and fills chamber with blood)
contracts
The normal heart rate is
(a)
What is cardiac output
(a)
