Question

what are the health risks associated with inhaling asbestos fibers?

reduced respiratory function and increased risk of lung cancer
increased risk of heart disease
no health risks at all
increased strength of lung tissue

Explanation:

Analyze the physiological effects of asbestos inhalation

Inhaling airborne asbestos fibers leads to their entrapment in lung tissues, causing progressive scarring (asbestosis), severely reduced respiratory function, and significantly elevated risks of lung cancer and mesothelioma.

Evaluate the given options

• Option 1: Correctly identifies reduced respiratory function and increased lung cancer risk.
• Option 2: Heart disease is not the primary direct risk associated with inhaling fibers.
• Option 3: Asbestos is a known carcinogen with severe health risks.
• Option 4: Fibers cause scarring and damage, not increased tissue strength.

Answer:

• Reduced respiratory function and increased risk of lung cancer (Correct answer)
• Increased risk of heart disease
• No health risks at all
• Increased strength of lung tissue
