Correct Answer: D

Rationale: The suspensory ligament of the ovary (infundibulopelvic ligament) anchors it to the pelvic wall, carrying vessels. 'Suspensory ligament,' is correct, per anatomy texts like Moore, distinct from other supports. 'Broad ligament,' encloses tubes and ovaries, not a direct anchor. 'Ovarian ligament,' connects ovary to uterus. 'Round ligament,' supports the uterus. The suspensory ligament's pelvic attachment makes D the accurate answer.

Correct Answer: D

Rationale: The kidney excretes nitrogenous wastes from protein metabolism. 'Carbon dioxide,' is correct as the exception, expelled by lungs, per physiology (e.g., Guyton). 'Urea,' 'Uric acid,' and 'Creatinine,' are renal excretions from amino acid and muscle breakdown. CO2's respiratory elimination contrasts with the kidney's nitrogenous waste role, making D the accurate answer.

Correct Answer: D

Rationale: The respiratory system conducts air for gas exchange. 'Gall bladder,' is correct as the exception, a digestive organ, per anatomy (e.g., Moore). 'Pharynx,' channels air and food. 'Trachea,' is the windpipe. 'Bronchi,' branch into lungs. Gall bladder's irrelevance to respiration makes D the precise answer.

Correct Answer: C

Rationale: Special senses are complex, receptor-specific (vision, hearing, taste, smell, balance). 'Touch,' is correct as the exception, a general somatic sense, per physiology (e.g., Costanzo). 'Vision,' 'Hearing,' and 'Taste,' are special. Touch's broad mechanoreception distinguishes C as the precise answer.
