Which of the following is listed as one of the 12 organ systems that can be examined?

• A. Cardiovascular
• B. Psychiatric
• C. Integumentary
• D. Endocrine

Answer: (B)

Organ-system based exams organize findings by distinct areas of the body, and in many standard checklists mental health is treated as its own category—the psychiatric system. This means the evaluation includes mood and affect, speech, thought processes, cognition, memory, orientation, and behavior, just like the cardiovascular or integumentary systems are evaluated for their respective functions. Including psychiatric as a separate system ensures mental health is assessed systematically alongside other physical systems. So, the option reflecting psychiatric fits the template of the 12 organ systems commonly used in exam checklists.
