Correct Answer is D
Explanation
A. Blocking the arterial walls from absorbing electrolytes: The respiratory system does not affect the absorption of electrolytes in this manner.
B. Preventing the absorption of sodium and potassium: The respiratory system does not regulate sodium and potassium absorption directly.
C. Regulating the excretion or reabsorption of H and HCO3: This function is performed by the kidneys, not the respiratory system.
D. Increasing ventilation to drop the H ion level: The respiratory system compensates for acid-base imbalances by increasing ventilation (hyperventilation) to lower the hydrogen ion (H⁺) level and reduce acidity.
Correct Answer is C
Explanation
A. Calculi form in the kidney and potentially travel into the ureter: This describes nephrolithiasis, not acute glomerulonephritis.
B. The renal pelvis and interstitium become infected: This describes pyelonephritis, not glomerulonephritis.
C. Antigen-antibody complexes cause nephron dysfunction: Acute glomerulonephritis occurs when immune complexes are deposited in the glomeruli, leading to inflammation and impaired kidney function.
D. Bacteria invade and grow in the urethra: This describes a urinary tract infection (UTI), not glomerulonephritis.
