Which body entry route is described by absorption?

• A. Inhalation
• B. The skin and eyes
• C. Ingestion
• D. Injection

Answer: (B)

Absorption is the entry route where a chemical moves into the body mainly through contact with the skin or mucous membranes, particularly the eyes. That means substances can pass through the skin or eye tissues and reach the bloodstream, making dermal and ocular exposures forms of absorption. Inhalation involves breathing contaminants into the lungs, ingestion is swallowing them into the digestive system, and injection introduces a substance directly through the skin into tissue or blood. So, the entry route described by absorption is through the skin and eyes, which is why dermal and ocular exposures are treated as absorption in hazardous materials contexts.
