Heart sound
S1:The sound closing mitral &tricuspid valves
S2: The sound closing aortic & pulmonary value
S3: The sound of filling of ventricular
S4: The sound of atrial contraction
End diastolic volume
Volume of blood in the ventricle before contraction
End systolic volume
Volume of blood in ventricle after contraction
Stroke volume
Edv-esv
Cardiac output
Volume of blood pumped by each ventricle per minute
Cardiac output= heart rate* stroke volume
Preload
Volume of blood received by the heart
Afterload
Amount of resistance the heart must overcome when ejecting blood
Venous return
The volume of blood returning back to the heart
