is the amount of blood pumped out by each ventricle in one minute.
Heart rate, stroke volume
cardiac output depend on _____ _____ and _____ ______.
Cardiac output= Heart rate х Stroke Volume
Mathematical relationship between cardiac output, heart rate, and stroke rate is _______ .
The number of times the heart beats in one minute.
______ ______ is the amount of blood pumped by each ventricle with each heart beat.
75 ml / beat
___ is the average stroke volume in adult at rest.
Stroke volume= EDV-ESV
Mathematical relationship between EDV and ESV:
Increased stretch in muscle fibers by increased blood volume returning to the heart, results in greater force of contraction which increases stroke volume.
The relationship between venous return and stroke volume is:
Increased _______ _______ on heart rate and stroke volume increases contractility of cardiac myocytes.
Increased ______ ______ on heart rate and stroke volume does not directly change stroke volume because the ventricular myocytes are only sparsely innervated by parasympathetic nerves.
