cardiovascular/respiration

Question 1

Short term effects of exercise -

Answer 1

• increase stroke volume
• Increase hr
• increase cardiac output
• increase bpm
• increase blood pressure

Question 2

Long term effects of regular exercise -

Answer 2

• Decrease resting hr
• Increase cardiac output and stroke volume
• Quicker recovery rate
• Lower blood pressure

Question 3

Define EPOC

Answer 3

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

Question 4

Define tidal volume -

Answer 4

How much you are breathing in and out.

Question 5

Define residual volume -

Answer 5

The amount of oxygen that will always be left in your lungs.

Question 6

Define Expiratory reserve volume

Answer 6

The amount of air you could exhale.

Question 7

Define inspiratory reserve volume

Answer 7

The amount of air you could inhale.

Question 8

Vital capacity

Answer 8

The highest amount of volume you could inhale and exhale in one breath.

Question 9

Define recovery rate

Answer 9

The time it takes for your heart to return to resting heart rate after exercise.

Question 10

Define heart rate

Answer 10

The amount of beats per minute.

Question 11

Define stroke volume

Answer 11

The amount of blood ejected by the heart in 1 beat.

Question 12

Define resting heart rate

Answer 12

The amount of times your heart beats at rest.

Question 13

Define cardiac output

Answer 13

The amount of blood ejected out of the heart in one minute.

Question 14

Define blood pressure

Answer 14

The force the blood travels through the arteries.

Question 15

Cardiac output equation

Answer 15

cardiac output = heart rate x stroke volume

Question 16

What movement occurs during the process of inspiration?

Answer 16

Intercostal muscles and diaphragm contracts (flattens)

Rib cage rises (goes up and out)

Question 17

What is the correct definition for cardiac output?

Answer 17

Amount of blood pumped out of the heart per minute

Question 18

The volume of blood leaving the heart per beat is called.

Answer 18

Stroke volume

Question 22

Which term is used to describe the movement of gases from an area of high concentration to an area of low concentration?

Answer 22

Diffusion

Question 23

Where would you find the intercostal muscles?

Answer 23

Between the ribs

Question 24

Oxygen debt can occur as a result of exercise. When would a 1500 metres runner experience Oxygen debt?

Answer 24

At the end of the race

Question 25
