cardiovascular system Flashcards
what is the equation of cardiac output
heart rate x stroke volume
what is the definition of cardiac output
volume of blood ejected by the heart per minute
what is the definition of heart rate
number of times the heart beats per minute
what is the definition of stroke volume
volume of blood ejected from the heart per beat
how is heart rate reserve calculated
maximum hr- resting hr
how is recovery heart rate calculated
heart rate two mins after exercise - heart rate immediately after exercise
what is bradycardia
someone having a resting heart rate under 60bpm
how is maximum hr calculated
220-age
how can resting hr be measured
counting the number of times the heart beats in one min while at rest or when exercising
oxygen in transported with the body in association with
haemoglobin
myoglobin
what is haemoglobin
oxygen carrying component of red blood cells
what is myoglobin
the oxygen carrying component of the muscle tissue
what is the Bohr shift on a graph
the line shifiting to the right as the conditions within the blood become more acidic during higher intensity exercise
factors influencing the Bohr shift
increase in co2
decrease in ph
increase in temperature
what is cardiovascular drift
the increase in heart rate which occurs despite no change in the intensity of exercise
