30
Q

What does the heart do

A

Pumps blood around the body
Receives blood from the veins
Pumps blood under high pressure into the arteries

31
Q

What keeps blood flowing in one direction through the heart

A

Valves, bicuspid, tricuspid

32
Q

Explain why the walls of the ventricles are thicker than the atria

A

Ventricles pump blood around the body at high pressure

33
Q

Explain why the walls of of the left ventricle is thicker than the wall of the right ventricle

A

Left ventricle pumps blood around the body at a higher pressure while the right ventricle pumps it at a lower pressure

34
Q

What happens to your heart when you get excited or exercise
Explain why

A

Your beats faster because you need more blood to transport oxygen and glucose around the body
Adrenaline can also be released to prepare the body for more activity part of this will be increasing heart rate to increase oxygen and glucose supply to the muscled

35
Q

What is the structure of the red blood cell

A

Red blood cells are very small and have no nucleus
They’re bioconcave in shape giving them a large surface area
They contain an iron pigment called haemoglobin which can pick up oxygen

36
Q

Function of red blood cell

A

When oxygen combines with haemoglobin it forms oxyhaemoglobin which is bright red
When oxygen is released to the tissues it turns purple

37
Q

White blood cell structure

A

Are slightly bigger than red blood cells
Come in many different types of

38
Q

White blood cell function

A

They protect the body
They’re able to defeat bacteria and then destroy them before they harm the body
Phagocytosis is when they engulf the bacteria to destroy them before
They produce antibodies. These protect is from infection. They work by making bacteria cells stick together so that is is easier to kill them and some others release toxins which neutralize the poison released by the bacteria

39
Q

Platelets structure

A

Tiny cell fragments

40
Q

Platelets function

A

They’re carried around the body and usually do nothing
If the blood is exposed to the air in a cut the platelets help to form a network of fibers at the cut, called a clot
This prevents blood being lost from the cut and stops bacteria and dirt getting in
The clot hardens to a scab. This keeps the wound clean while new skin grows

41
Q

Plasma structure

A

The liquid portion of the blood
Yellowish in colour

42
Q

Platelets function

A

It makes up around 55% of blood volume
It’s mainly water but contain dissolved substances including: digested food, hormones and wastes like carbon dioxide

43
Q

How can exercise reduce stress

A

Increased sense of well being as exercise stimulates the release of chemicals similar to morphine which creates a type of high

44
Q

If a man who has been resting starts doing some strenuous exercise what is the effect on the rate at which his heart beats

A

It will increase a lot

45
Q

Does a fit or unfit person have a higher heartbeat rate on average?

A

An average unfit person has a higher heart rate

46
Q

1o A fit heart pumps a larger volume of blood with each ‘beat’ than an unfit heart. Can you suggest why it is an advantage to be fit?

A

The heart uses less energy to pump more which will keep you healthy.

47
Q

What effect does exercise semetimes have on blood pressure, and why is it important?

A

Exercise widens the arteries and the build up of fatty deposit is less likely, this reduces heart disease from

48
Q

A middle aged man who was overweight was not only put on a diet by his doctor, but was also told to do regular exercise

A

Being overweight and not exercising has a risk of suffering from heart disease from high blood pressure

49
Q

What significant result was obtained from the London transport study, and what do you think is the reason for it? Why might the information be misleading?

A

Drivers sit down all day and conductors run up stairs daily
It doesn’t say about genetics, lifestyle or diet

50
Q

• List as many things as you can think of that can lead to heart disease

A

Diet
smoking
Stress

51
Q
  1. How do you think you can help avoid heart disease?
A

Have a healthy diet
Exercise
Relax mor destress

52
Q

At which ages do men and women show the same blood cholesterol level?

A

21-22yrs
47-48yrs

53
Q
  1. Use the information in the graphs to explain why the death rate for men, from coronary heart disease, is higher than the death rate for women, between the 25 and 45.
A

They have a higher level of cholesterol and high cholesterol is linked to heart disease

54
Q
  1. Use the graphs to determine the level of blood cholesterol that would keep the death rate, from coronary heart disease, at a minimum:
A

3-4 arbitrary units any higher incleases death

55
Q
  1. What does your answer suggest about cholesterol as the only cause of coronary heart disease?
A

The are other things that cause heart disease like genetics, Litestyle, diet
