Which route of entry describes absorption through the skin?

Explanation:
Absorption is the route of entry through the skin. When a chemical contacts the skin, it can diffuse through the skin’s layers and enter the bloodstream, especially if the substance is lipid-soluble or very small. This dermal absorption is distinct from inhalation (through the lungs), ingestion (through the mouth into the digestive system), and injection (directly into tissue or bloodstream). Dermal exposure depends on factors like how long the skin is in contact with the chemical, the chemical’s properties, skin condition, and whether protective barriers are used. Wearing proper gloves and protective clothing helps minimize this risk.
