cardiovascular/respiration Flashcards
Short term effects of exercise -
- increase stroke volume
- Increase hr
- increase cardiac output
- increase bpm
- increase blood pressure
Long term effects of regular exercise -
- Decrease resting hr
- Increase cardiac output and stroke volume
- Quicker recovery rate
- Lower blood pressure
Define EPOC
EPOC is the measurement of breathing. It shows how you are breathing and whether its aerobic or anaerobic. It also shows that during anaerobic respiration you build up an oxygen debt. You need to pay that off. That is why you continue breathing heavily after exercise. It can also be used to measure fitness
Define tidal volume -
How much you are breathing in and out.
Define residual volume -
The amount of oxygen that will always be left in your lungs.
Define Expiratory reserve volume
The amount of air you could exhale.
Define inspiratory reserve volume
The amount of air you could inhale.
Vital capacity
The highest amount of volume you could inhale and exhale in one breath.
Define recovery rate
The time it takes for your heart to return to resting heart rate after exercise.
Define heart rate
The amount of beats per minute.
Define stroke volume
The amount of blood ejected by the heart in 1 beat.
Define resting heart rate
The amount of times your heart beats at rest.
Define cardiac output
The amount of blood ejected out of the heart in one minute.
Define blood pressure
The force the blood travels through the arteries.
Cardiac output equation
cardiac output = heart rate x stroke volume
What movement occurs during the process of inspiration?
Intercostal muscles and diaphragm contracts (flattens)
Rib cage rises (goes up and out)
What is the correct definition for cardiac output?
Amount of blood pumped out of the heart per minute
The volume of blood leaving the heart per beat is called.
Stroke volume
Which blood vessel transports deoxygenated blood from the body to the right atrium
vena cava
Where in the respiratory system does gaseous exchange take place?
Alveoli
What key features of capillaries make them effective at gaseous exchange.
Large surface area , one cell thick
Which term is used to describe the movement of gases from an area of high concentration to an area of low concentration?
Diffusion
Where would you find the intercostal muscles?
Between the ribs
Oxygen debt can occur as a result of exercise. When would a 1500 metres runner experience Oxygen debt?
At the end of the race
