Q

How does smoking increase your blood pressure?

A
  1. Tobacco smoke contains carbon monoxide and nicotine.
  2. Carbon monoxide combines with haemoglobin in red blood cells and decreases its oxygen carrying capacity.
  3. The heart beats faster to compensate which puts a strain on the heart.
  4. Nicotine increases the heart rate

Q

How may saturated fat increase the blood pressure?

A
  1. Your liver makes cholesterol from saturated fat (fat in milk, butter, eggs, cheese, red meat and cream)
  2. Cholesterol is carried in the blood and may be deposited in artery walls
  3. These narrow the arteries and restrict blood flow. The blood pressure increases to force blood through the narrower gap.

Q

How is blood transported to all parts of the body at the correct pressure?
