The plane that divides a body part into anterior and posterior sections is the ___ plane.

Correct Answer: C

Rationale: The frontal (coronal) plane divides anterior (front) and posterior (back), not sagittal (B, left-right) or transverse (implied). A and C overlap terms, but C alone is standard. This plane's use in anatomy, like frontal brain sections, makes it correct.

Correct Answer: A

Rationale: The abdominopelvic cavity houses stomach, liver, and bladder, but not the heart, which is thoracic. Anatomy's cavity division ensures organ placement clarity, with the heart above the diaphragm.

Correct Answer: C

Rationale: The skeletal system produces blood cells via bone marrow (hematopoiesis), unlike cardiovascular (A, circulation), muscular (B, movement), or integumentary (D, skin). Anatomy links bones to blood formation, confirming C.

Correct Answer: B

Rationale: Meningitis inflames meninges around the brain and spinal cord, unlike pericarditis (heart), pleurisy (lungs), or peritonitis (abdomen). Anatomical membrane specificity ensures accurate diagnosis, making B correct.

Correct Answer: C

Rationale: Acute diseases onset rapidly and resolve quickly (e.g., flu), unlike chronic (A, prolonged), systemic (B, widespread), or local (D, limited). Anatomy and medicine use this for temporal classification, confirming C.
