Unit 1: CV System Part G Flashcards
1
Q
stroke volume
A
Volume of blood ejected from each ventricle
2
Q
Cardiac Output
A
Volume of blood ejected by each ventricle over time (i.e. rate at which each ventricle pumps blood)
3
Q
How is cardiac output determined?
A
Determined by the rate at which the ventricles contract (heart rate) and the volume of blood
pumped per contraction (stroke volume)
4
Q
How can you calculate stroke volume?
A
EDV- ESV
5
Q
End Diastolic Volume (EDV)
A
amount of blood in each ventricle at the end
of the ventricular relaxation period and, just prior to the start of ventricular contraction.
On average, at rest = 135mL
6
Q
End Systolic Volume (ESV)
A
amount of blood left in each ventricle just after
ventricular ejection
On average, at rest = 65 mL.
