Smokers have shorter breath due to

Explanation:

• Emphysema is a chronic disorder in which alveolar walls are damaged due to which respiratory surface is decreased.
• One of the major causes of this is cigarette smoking.
• The person experiences shorter breaths because of the reduced respiratory surface.
• The alveolar walls get damaged and over time they rupture.

Important Points

Arteriosclerosis:

• Coronary Artery Disease, often referred to as atherosclerosis, affects the vessels that supply blood to the heart muscle.
• It is caused by deposits of calcium, fat, cholesterol and fibrous tissues, which makes the lumen of arteries narrower.

Hypertension:

• Hypertension is the term for blood pressure that is higher than normal (120/80).
• In this measurement 120 mm Hg is the systolic, or pumping, pressure and 80 mm Hg is the diastolic, or resting, pressure.
• If repeated checks of blood pressure of an individual are 140/90 (140 over 90) or higher, it shows hypertension.

Cough:

• A cough is a forceful expulsion of air from the lungs that helps to clear secretions, foreign bodies, and irritants from the airway.
