Smoking damages the Cardiovascular System and increases the risk of:
- When damage occurs to the artery wall, white blood cells move in.
- Over time more white blood cells/lipids/connective tissue build up to form a fibrous plaque forming an Atheroma.
- Atherosclerosis is the hardening of arteries due to the atheromas forming.
- Nicotine increases blood pressure causing more damage meaning more atheromas.
'C' 'H' 'D':
- Caused when lots of atheromas form in the coronary arteries.
- Reduces flow of oxygen causing angina or a heart attack.
- Smoking increases Carbon Monoxide levels that bind to Haemoglobin reducing oxygen delivered to tissues even more.
- Nicotine makes platelets sticky, increasing the chance of blood clots forming.
- More atheromas means more risk of blood clots forming.
- If a blood clot forms in…
