transport of blood gases
In this section you need to know the following;
Roles of haemoglobin and myoglobin
Transport of oxygen – Bohr shift
Pulmonary and systematic circulation related to the various blood vessels (arteries/arterioles/ capillaries/venules and veins)
Generation of blood pressures/velocities
Venous return mechanism
Redistribution of blood/vascular shunting
Arterio-venous oxygen difference (A-VO2 diff).

Bohr Shift
Questions about the Bohr shift will often ask for the causes of the shift to the right and will possibly display a graph.

blood vessels, pressures and velocities
You will need to know the characteristics of each blood vessel and be able to relate them to its function.
Make sure that you read the question carefully as questions about blood velocity will usually test your knowledge about velocity from capillaries to the veins.

venous return mechanism
Questions here often ask you to describe the venous return mechanisms. Ensure you use correct terminology for example skeletal muscle pump.
More recent questions will ask you about the effects of exercise on venous return.

vascular shunting
Questions here often ask you to interpret a table and ask why and how blood distribution occurs in the body. When answering questions on this topic you must remember to use the key terms vasodilation, vasoconstriction, pre capillary sphincter.
You must remember to tell the examiner where there is increased blood flow and where there is reduced blood flow, common questions want you to explain more to the muscle and less to the non essential organs. You may also get asked to explain why you should not eat prior to exercise. Don't forget that you may be asked about blood flow to the brain and skin (Radiation)

A-VO2 difference
Questions here will ask you to define A-VO2 max and explain how this will change during exercise and the effect on the performer.
