• Smoking accelerates the process of atherosclerosis (narrowing of the arteries), which can lead to a heart attack.
• Smoking can also increase the risk of blood clots, which can block arteries

• Cigarette smoking speeds up the process of atherosclerosis by damaging the cells lining the blood vessels and heart.
•Cigarette smoking can increase your risk of dangerous blood clots, both because of the atherosclerosis and also because smoking causes blood platelets to clump together.
• No matter how long you've been smoking, quitting will reduce your chances of having a heart attack.
• Even among people with heart disease, the risk also drops sharply one year after quitting smoking, and it continues to decline over time, but the risk does not return to normal.
What is pneumonia?
~A serious infection of the lung tissue by one of many different micro-organisms causing an inflammation in the lungs.
- The infection causes the air sacs (alveoli) and smaller airways in your lungs to become inflamed and fill with fluid.

Lobar pneumonia
- inflammation affects a section, lobe part of a lung Bronchopneumonia
- a patchy infection occurring throughout the lungs.
- The term double pneumonia means both lungs are affected.
