Heart diagram
What occurs at the area labeled C on the graph
AV valve closes
What occurs at the area labeled "B" on the graph? A) ventricular ejection occurs B) AV valve closes C) semilunar valve opens D) semilunar valve closes E) AV valve opens
Semi lunar valve closes
The phase in the cardiac cycle when the mitrial valve is closed and the aortic valve is open is the
Systolic ejection phase
What occurs at A on the graph
semilunar valve opens
What volume is labeled "E" on the graph?
stroke volume
What occurs on the circle labeled 4 on the graph
isovolumetric ventricular contraction
What occurs at the circle labeled 7 on the graph
isovolumetric ventricular relaxation
What is occurring in the left atrium at the circle labeled 2 on the graph
left atrium is in systole
What occurs at the circled label "5" on the graph?
peak systolic pressure
What occurs at the area labeled "D" on the graph?
both AV valve opens and diastolic refilling begins
What volume is labeled F on the graph
end diastolic volume
What volume is labeled G on the graph
end systolic volume
