- Protecting the body
- blood contains cells and antibodies that fight infection, and clotting agents to stop bleeding
- The heart
- Upper chamber
- Atrium

- oxygenated blood
- Right side
- De-oxygenated blood
- Comes from the body, goes to the body
- De-oxygenated blood
- Upper chamber
- The blood
- Contains a red-coloured compund called HAEMOGLOBIN
- This bonds with OXGEN to form OXYHAEMOGLOBIN
- Contains a red-coloured compund called HAEMOGLOBIN
- Blood vessels
- Arteries
- Sends blood AWAY from the heart
- Veins
- Takes blood TO the heart
- Capillaries
- Thin for OXYGEN and CARBON DIOXIDE to DIFFUSE
- Arteries
- Heart beat
- TWO beating sounds
- 1st = SYSTOLE
- Made by the VENTRICLES
- Pushing blood at high pressure into ARTERIES
- Made by the VENTRICLES
- 2nd = DIASTOLE
- Made by the ATRIUMS
- Pushing blood down into the VENTRICLES
- Made by the ATRIUMS
- 1st = SYSTOLE
- TWO beating sounds
- Blood Pressure

- Some drugs may increase blood pressure so people have to take ANOTHER drug to CONTROL it
- Prescription drugs
- REDUCING high blood pressure
- Effects of EXERCISE on the CV systen
- LONG TERM
- Decreased RESTING heart rate
- Heart recovery rate DECREASES
- INCREASED stroke volume
- Cardiac output INCREASES
- Blood pressure DECREASES
- HEALTHY veins and arteries
- IMMEDIATE
- Breathing is FASTER
- Body temperature INCREASES
- Sweating BEGINS
- Muscles begin to ACHE
- LONG TERM
- Effect of LIFESTYLE on the CV system
- POSITIVE
