- High BP and Heart Disease
- High BP
- Causedby smokin-g
- Carbon monoxide
- CO combines with haemoglobin in red blood cells
- This reduces their ability to carry oxygen and supply the cells and tissues with oxygen
- This deprives the cells and tissues of oxygen, so the heart has to make up for it so that the cells and tissues get enough O2.
- The heart does this by beating faster and more frequently, causing BP to increase
- This deprives the cells and tissues of oxygen, so the heart has to make up for it so that the cells and tissues get enough O2.
- This reduces their ability to carry oxygen and supply the cells and tissues with oxygen
- CO combines with haemoglobin in red blood cells
- Nicotine
- Directly increases heart rate. i.e. Nicotine causes the heart to beat faster.
- This increases BP, as heart beats more often, so blood is at a higher pressure.

- Carbon monoxide
- Causedby smokin-g
- Heart disease
- Any disease that affects the heart. e.g. heart attacks
- Eating too much salt
- Increases BP.
- Which increases the risk of damage in the arteries.
- This damage can encourage the build up of plaques, which can lead to a heart attack
- Which increases the risk of damage in the arteries.
- Increases BP.
- NarrowArteries
- The coronary arteries supply the heart muscle with blood
- If it's narrowed, blood flow is restricted and the heart muscle receives less oxygen
- As said before, this causes a heart attack
- If a 'thrombosis' happens in an already narrow coronary artery...
- Blood flow to the heart might be blocked completely
- This will cut of oxygen supply completely for one area of the heart muscle.
- AND THAT CAUSES A HEART ATTACK!
- This will cut of oxygen supply completely for one area of the heart muscle.
- Blood flow to the heart might be blocked completely

- High BP
- Thrombosis: a blood clot in a part of the circulatory system
