Answer 1

The amount of blood discharged from the L or R ventricle per minute

HR x SV = CO

Question 2

What is Systolic volume?

Answer 2

SV- amount of blood pumped from the L ventricle per beat (oxygenated)
-End diastolic volume = preload -> water in damn- volume
-Average aortic BP = afterload - pressure heart pumps against to eject blood - pressure
-Strength (contractility) - norepinephrine and epi and direct sympathetic stimulation to heart (frank stearling stretch)
