Which system is NOT included in a physical examination?

The endocrine system is not typically assessed as a separate system during a routine physical examination in emergency or acute care settings. While signs of endocrine disorders may be observed (such as changes in skin, weight, or energy levels), the examination does not generally include specific tests or assessments dedicated exclusively to the endocrine system unless there is a presenting concern or history related to hormonal imbalance or dysfunction.

In contrast, the neurological, respiratory, and cardiovascular systems are key components of a standard physical examination. The neurological examination assesses cognitive function, motor strength, reflexes, and sensory function. The respiratory examination involves evaluating breathing patterns, lung sounds, and oxygenation. The cardiovascular examination focuses on heart sounds, rhythm, and blood pressure. These systems undergo thorough examination because they relate directly to common presenting complaints and potential life-threatening conditions that are typically addressed in emergency settings.
