The volume of blood pumped out of the heart with each beat, usually measured in millilitres per beat.
Used by AQA and OCR
Paper 1
The volume of blood pumped out of the left ventricle with each heartbeat, usually measured in ml per beat.
Revise: Cardiac output and heart rateStroke volume (SV) is the volume of blood pumped out of the left ventricle with each heartbeat, usually measured in ml per beat. The left ventricle is the chamber that pumps oxygenated blood towards the body.
The volume of blood pumped out of the heart with each beat.
Paper 1
The volume of blood pumped out of the left ventricle in one beat, usually measured in millilitres per beat.
Revise: Cardiovascular System Structure and FunctionStroke volume is the volume of blood pumped out of the left ventricle in one beat. Cardiac output is the volume pumped out of the left ventricle in one minute.
The volume of blood pumped out of the heart in one beat.
Distinguish blood per beat (stroke volume), beats per minute (heart rate) and blood per minute (cardiac output).
Show the multiplication when calculating cardiac output. If stroke volume is in ml per beat, the result is in ml/min; divide by 1000 to convert to L/min.
When explaining bradycardia, link increased stroke volume to fewer beats being needed at rest. Do not confuse a lower resting heart rate with the immediate rise in heart rate during exercise.
