Q

Identify the role of a Vein?

A

Carry blood to the heart.

17
Q

Identify the role of a Capillary?

A

Allow the exchange of Carbon dioxide and Oxygen.

18
Q

Identify a characteristic of an Artery?

A

Strong elastic walls, high pressured blood.

19
Q

Identify a characteristic of a Vein?

A

Thinner walls than arteries, valves to keep blood carrying in the correct direction.

20
Q

What four components make up blood?

A

Red blood cells, White blood cells, Plasma and Platelets

21
Q

Describe the role of red blood cells?

A

Contain Haemaglobin that carries and delivers oxygen around the body and to working muscles.

22
Q

Describe the role of White blood cells?

A

Defend the body from infection.

23
Q

Describe the function of the Diaphragm during inspiration?

A

Diaphragm contracts and flattens ad pulls the bottom of the lungs down.

24
Q

Describe the function of the intercostal muscles during inspiration?

A

Intercostal muscles contract and pull the ribs down and lungs outwards.

25
Q

Explain what happens to the size of the lungs during insipration and expiration?

A

Lungs increase in size during inspiration and decrease in size during expiration.

26
Q

How much of the air that we inhale is made up of Oxygen?

A

21% Oxygen

27
Q

Define Gaseous exchange?

A

The delivery of oxygen from the lungs to the bloodstream and the removal of carbon dioxide from the tissues.

28
Q

What characteristics of alveoli and capillaries allows Gaseous exchange to occur?

A

Thin walls which allow for gases to pass through (Diffusion)

29
Q

During exercise what happens to the frequency of gaseous exchange?

A

The frequency increases as the body requires more oxygen and the body produces more carbon dioxide.

30
Q

Identify the two types of energy production?

A

Aerobic and Anaerobic energy production

31
Q

Describe Aerobic exercise?

A

Working at a low to moderate intensity. The body has time to use oxygen to produce energy.

32
Q

Describe Anaerobic exercise?

A

Working at a high intensity without oxygen. Production of energy is limited.

33
Q

Identify a bi-product of anaerobic energy production?

A

Lactic Acid

34
Q

What can build up as a result of Lactic acid?

A

Muscle soreness, muscle aches and cramp

35
Q

What two nutrients can be used as an energy source in aerobic energy production?

A

Carbohydrates and Fats
