cardiac output is __________.
amount of blood pumped out by the heart in liters per minute
stroke volume is ___________
the quantity of blood ejected with each heart beat
cardiac output equation is ________ x _________.
stroke volume X heart rate
maximal heart rate equation
220- age in years.
1 MET = how many ml of oxygen per kg body weight per minute?
3.5
fick equation: V02 = ____ X _______
q (cardiac output); a V02 difference.
arteriovenous oxygen difference is ____________
the difference in oxygen content between arterial and venous blood
tidal volume is the total amount of air ______ and ________ with each breath.
inhaled; exhaled
functional unit of the pulmonary system where gas exchange occurs:
alveoli
bradycardia
slow heart rate
what is myoglobin?
a protein that transports oxygen within the cell
Two adaptation that occur at higher altitudes
Hyperventilation
Increased cardiac output at rest due to higher heart rate
hyperoxic breathing:
breathing oxygen enriched gas mixtures during rest periods or following exercise
blood doping (mechanism)
running your blood through EPO and then shuttling it back into your body.
