The systemic circulation delivers blood around the body.
Aterioles
Capillary walls are only 1 cell thick to allow nutrients & waste products to
pass through the walls into & from the blood stream.
Veins have valves to prevent blood flowing backwards.
The upper chambers are called ‘atria’ or an ‘atrium’ & their role is to fill with
blood coming into the heart. The lower chambers are known as ‘ventricles’
their role is to contract so that blood is forced out to the lungs & the body.
Red blood cells give blood its colour.
Plasma contains dissolved substances such as salts, calcium, glucose,
hormones & waste products like carbon dioxide.
Heart Rate x Stroke Volume = Cardiac Output
During exercise blood flow could increase 30 times while oxygen delivery up
to 3 times.

The heart.
Transport, protection, temperature regulation & maintain the body’s equilibrium.
Haemoglobin.
Blood vessels.
Carbon dioxide, water & lactic acid.
Large stroke volume, low resting pulse, high cardiac output.
The force of blood against the artery walls.
Low resting pulse, high maximum heart rate, quick recovery.
Increased cappillarisation, increased stroke volume, increased cardiac output, increased
oxygen transport.
Cardiac muscle.
Arteries.
The volume of blood pumped out of the heart in 1 minute.
The amount of blood that leaves the heart per beat. If it is low fatigue will set in quickly as will
maximum heart rate as not enough blood will deliver enough oxygen for the demands of the
working muscles.The bigger it is the longer you can work before fatigue sets in as oxygen
requirements are being met.
Stamina/endurance/aerobic fitness.
