Q

Why do the ventricles have thicker walls in the atria?

A

Because they have to pump the blood further around the body, so more muscle is required

Q

Why does the left ventricle have thicker walls than the right ventricle?

A

Because the left ventricle pumps blood to the whole body, where is the right ventricle pumps blood to the lungs.

Q

What is oxygenated blood attached to?

A

Haemoglobin

19
Q

Where do red blood cells pick up oxygen?

A

In the lungs and alveoli

20
Q

Label the artery, vein and capillary.

A

Artery
A) smooth muscle with elastic muscle fibres.
B) endothelium
C) lumen
D)fibrous outer layer.
Vein
A) smooth muscle with elastic fibres
B) endothelium
C) fibrous outer layer
D) lumen.
Capillary
A) one cell thick wall
B)lumen

21
Q

Which blood vessel carry blood away from the heart?

A

Arteries

22
Q

Which blood vessels carry blood towards the heart?

A

Veins.

23
Q

Why do arteries have strong walls?

A

To withstand blood at a high pressure.

24
Q

What is the job of an artery?

A

To pump oxygenated blood away from the heart to the rest of the body.

25
Q

What is the structure of the wall of the artery?

A

Big tick wall. Elastic.

26
Q

How does the structure of an artery help them do their job?

A

Pump blood at a high pressure efficiently.

27
Q

What is the job of a capillary?

A

to allow gases and nutrients to pass through easily.

28
Q

What is the structure of the wall of a capillary?

A

Single cell wall very thin.

29
Q

How does the structure of a capillary help them do their job?

A

Very small so they can penetrate every part of the body.

30
Q

What is the job of a vein?

A

To pump deoxygenated blood towards the heart from the lungs in the body.

31
Q

What is the structure of a wall of a vein?

A

Thin, smooth wall with a large lumen.

32
Q

How does the structure of a vein help it do its job?

A

They can pump blood at a lower pressure smooth, will provide less friction.

33
Q

What is the definition of stoke volume? (SV) and the approximate resting value?

A

The volume of blood pumped out of the heart per beat. 70ml ( average fitness) 90ml athlete

34
Q

What is the definition of heart rate? (HR) and the approximate resting value?

A

The number of times the heart hearts per minute. 70bpm (average)

35
Q

What is the definition of cardiac output? (CO) And the approximate resting value?

A

The volume pumped out of the heart per minute. 4.9L/min (average)

36
Q

What is the equation linking SV,HR and CO

A

CO = SV x HR

37
Q

What are the 4 components of blood? And what percentage of the blood are they?

A

1) plasma (55%)
2) red blood cells (44%)
3) white blood cells ( >1%)
4) platelets (>1%)

38
Q

What is the function of the plasma?

A

The liquid component of the blood. It’s jobs is to transport nutrients such as glucose.

39
Q

What is the function of the red blood cells?

A

Contain haemoglobin. Their job is to transport oxygen. ( and CO2)

40
Q

What is the function of white blood cells?

A

To fight infections and bacteria, producing antibodies to do so.

41
Q

What is the function of platelets?

A

To clot the blood

42
Q

What is the role of haemoglobin?

A

1) its a protein found in red blood cells.
2) high (affinity) attraction for oxygen.
3) oxygen attaches to the haemoglobin. (Oxyhemoglobin) and gets transported around the body.
4) carbon dioxide attaches to haemoglobin. (carbaminohaemoglobin)
