The integumentary system includes:

Correct Answer: C

Rationale: The integumentary system encompasses skin, hair, and nails, forming a protective barrier and sensory interface. Unlike skeletal or nervous components, it regulates temperature and defends against pathogens. This system's health is vital, with clinicians assessing it for signs of infection or injury, leveraging its external role to maintain overall well-being.

Correct Answer: A

Rationale: The coronal plane divides the body into front and back, isolating anterior from posterior regions. This orientation is vital for frontal assessments like chest exams offering a clear view of forward-facing structures. It enhances medical precision, guiding interventions by delineating these key anatomical zones.

Correct Answer: B

Rationale: Respiration transforms nutrients into energy via cellular processes, primarily in mitochondria, fueling bodily activities. Distinct from digestion's breakdown or excretion's waste removal, it's the energy engine. Nurses monitor its efficiency like in respiratory distress ensuring cells power life's demands seamlessly.

Correct Answer: B

Rationale: Arteries transport oxygen-rich blood from the heart to tissues, powering cellular function. Unlike veins or capillaries, they're built for pressure, driving circulation. Nurses track arterial health like in hypertension ensuring oxygen delivery supports bodily vitality.

Correct Answer: B

Rationale: The endocrine system secretes hormones to regulate processes like metabolism and growth. Distinct from circulatory or nervous roles, it's a chemical messenger network. Nurses monitor it like in diabetes ensuring hormonal balance maintains bodily harmony.
