Transportation in Plants and Circulation in Animals - Formula Sheet
Physiological Relations and Expressions
Respiratory Quotient (RQ):
RQ = (Volume of CO2 Liberated) / (Volume of O2 Consumed)
Blood Pressure Expression:
Blood Pressure = Systolic Pressure / Diastolic Pressure (Normal resting value = 120 / 80 mm Hg)
Cardiac Cycle Duration Breakdown:
Total Cardiac Cycle Time = Atrial Systole (0.1 s) + Ventricular Systole (0.3 s) + Joint Diastole (0.4 s) = 0.8 s
Heart Rate Relation:
Average Human Resting Heart Beat = 72 to 75 beats per minute
Whole Blood Composition Ratio:
Blood Volume = Fluid Plasma (~55%) + Formed Cellular Elements (~45%)
