What is the meaning of the root "iatr/o" in medical terminology?

• A. Treatment
• B. Distinctive
• C. Below
• D. Immunity

Answer: (A)

The root "iatr/o" in medical terminology is derived from the Greek word "iatros," which means "physician" or "healer." This root is commonly associated with concepts of treatment, care, and medicine. Thus, in various medical terms, "iatr/o" signifies aspects related to medical treatments or therapies, such as in "iatrogenic," which refers to a condition caused by medical treatment.

While the other options—distinctive, below, and immunity—refer to different roots and meanings in medical terminology, they do not align with the focus on treatment that "iatr/o" provides. Understanding roots like "iatr/o" is essential for building a foundational knowledge of medical terminology, as they often indicate the nature of health care interactions and procedures.
