The relative consistency of the body's internal environment is called

Correct Answer: C

Rationale: Homeostasis maintains internal stability (e.g., temperature), not hemostasis (A, clotting), regulation (B, broad), or systemic (D, body-wide). Anatomy and physiology emphasize this balance, critical for survival, confirming C.

Correct Answer: C

Rationale: Medial, means toward the body's midline e.g., the nose medial to the ears. Lateral is away from midline, proximal closer to attachment, superior above, and inferior below. In anatomical position, medial orients structures centrally, critical for describing symmetry and proximity, like heart medial to lungs, making C accurate.

Correct Answer: C

Rationale: Plasma , is blood's fluid portion, comprising water, proteins, and electrolytes, excluding cells like platelets. Interstitial and tissue fluid surround cells, intracellular is within. Anatomically, plasma (55% of blood) carries nutrients and waste, critical for circulation, making E the precise term.

Correct Answer: C

Rationale: This plane slices vertically from head to toe, separating the body's back from its front. It's a fundamental cut in anatomy, revealing dorsal structures like the spine versus ventral ones like the heart. Clinicians use it in imaging like frontal X-rays to differentiate anterior and posterior conditions, ensuring precise diagnostics. Unlike horizontal or midline divisions, it highlights the front-back axis, essential for mapping the body's layout and guiding interventions across its depth.

Correct Answer: D

Rationale: The musculo-skeletal system bones and muscles spans limbs, torso, and head, existing outside the body's major cavities. Unlike organs housed in dorsal or ventral spaces, it surrounds and supports these regions. Nurses assess it for injuries like fractures beyond cavity confines, focusing on its external framework role. This distribution ensures mobility and protection, distinct from cavity-bound systems, shaping care for structural integrity.
