Heart rate: - The number of times ventricles contract per minute Stroke volume: - The volume of blood ejected by each ventricle per beat. Cardiac output (Q): - The volume of blood ejected by each ventricle per minute. Q (L/min) = HR (b/min) x SV (L/b) Humans have.. - 5 L of blood in their body. NARP resting BPM - about 70 BPM (5 L/min ÷ 72 ml/beat) Endurance trained resting BPM

cardiac output (Q) - Answer-volume of blood ejected by each ventricle per minute Q (L/min) = HR (b/min) x SV (L/b) Q = HR x SV heart rate (HR) - Answer-number of times ventricles contract per minute blood pressure - Answer--pressure = flow x resistance -flow corresponds to Q, resistance corresponds to viscosity and diameter of blood vessels -highest when standing and lowest when laying down -at rest - systolic = 90-145 mmHG, diastolic = 40-85 mmHg (120/80 is norm, 90/50 is okay) -exercis...
