Blood vessels

Form follows function.

Read the following passage and see if you can predict what the 3 types of blood vessels may look like.

Artery Capillary Vein

Transports blood from the heart under high pressure to the body

Allows gases and other substances to pass through to get to the cells

Brings the blood back to the heart and keeps blood flowing in one direction under lower pressure

Plenary:

Describe the journey of a blood cell as it travels through the circulatory system. Descirbe the structure of the system.

37

Blood!

Starter:

In groups, discuss -• What is the function of blood?• How would you design blood to do it's job?

38

Objectives:

Know that

• Blood is made from several components, Red cells, White cells, Plasma and platelets

• The function of blood

Where do we go?

You have now looked at several topics about your body and health. Match the following words to the part(s) of blood concerned:

Red cells

White cells

Higher tier:

The immune system

Antibody production

Tissue rejection

Phagocytosis

45

1. Bacteria produce toxins (waste) that cause harm to your cells

2. They have a specific markers on their surface

46

How does your body respond?

47

Fighting Disease

• Consume the microbe• Produce antibodies to neutralise the microbe• Produce anti-toxins to neutralise the poisons

White blood cell

48

MO invades body

White blood cell recognises shape on MO surface

Antibodies are made

The antibodies stick to the MO surface because they are the same shape

Another type of white blood cell recognises the antibodies and 'eats' the MO

49

Only the correctly shaped antibody will fight each MO

51

Investigate - The healthy heart

Recovery rate investigation

Theory:

The heart is made from muscle. All muscles need exercise if they are to stay healthy. The heart has it's own blood supply. If a person does not exercise and also eats too much fat, the heart will be weaker and also have to work harder to pump blood around the body. This puts strain on the heart.

A way of measuring how healthy someone is is to see how long their heart takes to recover after vigorous exercise.

52

You need to know the following things:

• Starting pulse rate • How long it takes to recover to the

'resting' rate
