Responses (5) + Adaptations (7) of CV System (CV) Flashcards
State the 5 responses of the CV System
Increased cardiac output
Increased heart rate
Anticipatory heart rate increase
Increased blood pressure
Redirection of blood flow
State the 7 adaptations of the CV System
Increase stroke volume
Cardiac hypertrophy
Decreased resting heart rate
Capillarisation of skeletal muscle
Decrease in resting blood pressure
Decrease in heart rate recovery time
Increase in blood volume
Define increased cardiac output (response)
The more improved the heart becomes, the more blood can be pumped with each beat
Define increased heart rate (response)
As you start to exercise more, your heart will pump more because it is working harder
Define Anticipatory heart rate increase (response)
Before an event or something important, you get adrenaline which causes your heart rate to rise a bit.
Define increased blood pressure (response)
As you exercise more, the demand for blood increases meaning increased blood pressure
Define redirection of blood flow (response)
During exercise, blood goes to the muscles that are needed to be worked
Define increased stroke volume (adaptation)
The more improved your heart is, the more blood it can pump out with each beat
Define cardiac hypertrophy (adaptation)
The more your heart gets worked, the more improved it becomes which means its stronger and firm higher intensity more
Define decrease in resting heart rate (adaptation)
As your heart strengthen, your resting heart rate will decrease which means you’re fitter
Define decrease in resting blood pressure (adaptation)
As you’re resting, your blood pressure would be lower than the average person’s because you’re fitter
Define increase in blood volume (adaptation)
An increase in the amount of blood that’s in your body
Define capillarisation (adaptation)
More capillaries means more blood flow around the body
