Acute glomerulonephritis primarily involves which part of the kidney?

• A. Renal Tubules
• B. Glomerulus
• C. Renal Pelvis
• D. Calyces

Answer: (B)

Acute glomerulonephritis is a disease that targets the glomeruli, the filtering units of the kidney. The glomerulus is where plasma is filtered into Bowman's capsule, and inflammation here makes the capillary walls more permeable. This leads to leakage of red blood cells and protein into the urine and a reduced glomerular filtration rate. Because the inflammation is centered on the glomerulus, that part is the primary site involved. The other kidney structures—renal tubules, renal pelvis, and calyces—are not the main targets in this condition, though downstream effects can occur. Clinically, you’d expect hematuria, proteinuria, and signs of reduced filtration such as possible edema and hypertension.
