Question

Hello

Answer 1

Answer:

1. The cilia sweep out mucus and dirt so your lungs stay clear. Smoking temporarily paralyzes and even kills cilia. This makes you more at risk for infection. Smokers get more colds and respiratory infections than non-smokers.

2. Smoking inflames and irritates the lungs. Even one or two cigarettes cause irritation and coughing. Smoking also can destroy your lungs and lung tissue. This decreases the number of air spaces and blood vessels in the lungs, resulting in less oxygen to critical parts of your body.

3. This is for congestive heart failure; Smoking causes atherosclerosis, a buildup of fatty substances in your arteries. The blockages in your arteries makes it harder for the heart to pump blood. This excess strain weakens and damages the heart muscle.

If doesn't help here is this explanation Smoking increases the formation of plaque in blood vessels. Coronary Heart Diseaseoccurs when arteries that carry blood to the heart muscle are narrowed by plaque or blocked by clots. Chemicals in cigarette smoke cause the blood to thicken and form clots inside veins and arteries.

Hope it helps!!!
