Which term is the process by which waste is removed from the body?

• A. Absorption
• B. Distribution
• C. Sources of drugs
• D. Exertion

Answer: (D)

Excretion is the process by which waste is removed from the body. The kidneys filter blood to form urine and eliminate metabolic wastes and excess substances; the lungs expel carbon dioxide and water vapor; the skin releases water and salts in sweat; and the liver helps eliminate waste via bile into the digestive tract. In pharmacology, excretion describes how drugs are cleared from the body, influencing how long effects last. Absorption is the uptake of substances into the bloodstream, and distribution is how those substances move within the body. Exertion refers to physical effort and is not a method of waste removal.
