Blood Distribution at Rest - Brain: 13%, 720 mL Muscle: 21% 1200 mL Skin: 8.5%, 500 mL Kidneys: 19%, 1100 mL Abdomen: 24%, 1400 mL Heart: 4%, 250 mL If you measure systolic blood pressure, when would it be highest, standing, sitting or lying down? - standing Systolic pressure - It is the maximum pressure your heart exerts while beating Diastolic pressure - The pressure in the arteries when the heart is at rest

cardiac output (Q) - 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) - number of times ventricles contract per minute blood pressure - -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) -exercise - systolic increase...

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
