M4.
Award one mark for stating and one further mark for describing each function of blood within
the body (2×2).
•
Transport or carrying or supplying / blood or water or oxygen or nutrients or waste
products around the body.
•
Protection or it helps to fight disease or to clot the blood / eg antibodies or white
blood cells which fight infection are carried in the blood or platelets seal cuts and
wounds.
[4]
M5.
(i)
Award up to two marks for describing the transport function:
It carries glycogen/, water/, oxygen/ or nutrients throughout
the body/to the working muscle/and helps with the transport and
removal of waste/carbon dioxide/lactic acid/away from the working
muscle.
2
(ii)
Award up to two marks for describing the control of body
temperature function. The blood absorbs body heat/then carries
it to the skin and lungs/where it is released/veins dilate/to cool
you down.

M7.
(i)
Award one mark for each correctly described pulse point. Note that some
might be correctly named and for others a description of their exact location
may be accepted.
•
Radial pulse/at the base of the thumb on the inside of the wrist
•
Temporal pulse/just over the temple at the side of the forehead

(ii)
Award up to three marks for a correct explanation.
Examples:
•
The heart rate lets you know how quickly the blood is being pumped
around the body
•
This is effectively providing the energy to allow the body to exercise
•
There are certain zones or areas which the heart rate can be
increased to or worked in
•
The speed of your recovery rate is a general indicator of your
fitness levels
•
The quicker you are able to return your pulse to its resting rate
the fitter you are
•
Monitoring the rate can be used as a training indicator to make
sure you are working at the correct levels
•
Varying the pulse rate can be used relative to the principle of
overload
•
Safety aspects can be considered to ensure you are not working
at too high a level.
Accept the above plus any other suitable examples.
