Smoking

The lungs are the primary respiratory organs. They act as filters for the air the body breathes in and normally are a healthy pink color.

Filtering smoke from the air breathed in can do damage to the lung tissue as seen in a smoker’s lung. Over time, carbon molecules from inhaled smoke deposit in the lung tissue, giving it a blackened appearance.

Smoking can eventually lead to the formation of tumors and other serious lung diseases. Smoking has also been linked to diseases that affect the cardiovascular system, such as atherosclerosis, which can lead to a heart attack or stroke.
