D
Impossible to tell.

Slide 4 - Quiz

Slide 5 - Open question

B5: cardiovacular diseases



-Blood pressure: high or low.
-Blockages: heart attack; stroke etc.

Slide 8 - Slide

Low blood pressure
-Usually not much of a problem.
-Dizzyness; fainting; fatigue; light headaches.


Slide 9 - Slide

High blood pressure
-Walls of arteries develop tears.
-Cholesterol (fat) builds up in tears. 
-nosebleeds; severe headaches; problems with vision.

Slide 10 - Slide

Blockages
-A blood clot or cholesterol plaque(prop) blocks a blood vessel.
-Cells of affected organ do not receive nutrients+ O2. Waste products also build up.

Slide 11 - Slide

Blockages
-Blockage in coronary artery: heart attack.
-Blockage in brain capillary or carotid artery(halsslagader): stroke.
-Blockage in lung: Pulmonary emboly


Slide 12 - Slide

Causes
-Unhealthy diet: 
-Lots of fatty foods increase cholesterol level in blood.
-Too much salt increases blood pressure.
-Smoking causes constriction of vessels, which increases damage to arterial walls.
-Not enough exercise: higher blood pressure and weight.
-Genes which increase cholesterol level.

(balloon) Angioplasty (with stent):
-insert balloon to widen artery. Place 'cage' to keep it open.

-Insert a vein from elsewhere in the body, around the blockage.
