The field concerning the nature, effects, and detection of chemicals (poisons or drugs) in living organisms is called what?

• A. Trauma
• B. Tissue
• C. Sepsis
• D. Toxicology

Answer: (D)

Understanding how toxins and drugs affect the body and how we detect them is toxicology. This field looks at the chemical nature of substances, how they exert their effects, how dose relates to harm, how the body processes them, and the laboratory methods used to identify poisons or drugs in living organisms—an important part of clinical care and forensic investigations. The other terms don’t fit this description: trauma refers to physical injury, tissue is a body’s material, and sepsis is a dangerous infection response.
