Cardiac output formula
Cardiac output formula
Stroke Volume × Heart Rate
Cardiac output definition
Cardiac output definition
Amount of blood leaving heart per minute
Stroke volume definition
Stroke volume definition
Amount of blood ejected from heart per beat
Heart rate definition
Heart rate definition
Number of times heart beats per minute
Anticipatory rise
Anticipatory rise
HR increase before exercise due to adrenaline
Heart rate at rest
Heart rate at rest
At its lowest
Why HR increases sharply when exercise starts
Why HR increases sharply when exercise starts
Due to demand for oxygen
HR during continuous exercise
HR during continuous exercise
Levels/sustains to meet oxygen need
HR immediately after exercise
HR immediately after exercise
Decreases sharply as oxygen demand reduced
Tidal volume definition
Tidal volume definition
Air inspired or expired in a normal breath
Vital capacity definition
Vital capacity definition
Max air expired after max inspiration
Residual volume definition
Residual volume definition
Air remaining in lungs after forced maximal exhalation
Expiratory reserve volume
Expiratory reserve volume
Max air exhaled in addition to tidal volume
Inspiratory reserve volume
Inspiratory reserve volume
Max air inhaled in addition to tidal volume
Tidal volume during exercise
Tidal volume during exercise
Increases to meet O2 demand & remove CO2
