Inhalation is defined as which action?

• A. To take air into the lungs; to breathe in
• B. To exhale rapidly
• C. To absorb pesticides through the skin
• D. To ingest pesticides

Answer: (A)

Inhalation means taking air into the lungs—breathing in. This is a route of exposure where airborne substances can enter the respiratory system. It differs from exhaling, which is breathing out, and from dermal exposure (through the skin) or ingestion (swallowing). So the action described by inhalation is to take air into the lungs; to breathe in.
