Answer 1

Cardiac output(CO) is the amount of blood pumped by the heart per minute. It is depending on heart rate (HR) and stroke volume (SV).

Jay's cardiac output:

CO = HR (beats/min) × SV (L/beat)

CO = 4.9L/min (see calculation below)

CO = HR Cbeats/mm) X SV CL14/ beat) = 70 x 0.870 (When Converting formal to Liter. 20.070) = 4.900 L/minuta = 4.9 L/minde SHOT ON REDMI 7 AT DUAL CAMERA
