Final answer:
Acute glomerulonephritis is characterized by oliguria, generalized edema, hematuria, and proteinuria, symptoms that reflect the damage and inflammation of the kidney's glomeruli.
Step-by-step explanation:
The clinical manifestations of acute glomerulonephritis include oliguria (an abnormally small amount of urine) and generalized edema (swelling), as well as hematuria (blood in the urine) and proteinuria (protein in the urine). These symptoms are indicative of inflammation and damage to the glomeruli, which are part of the nephrons in the kidneys. Oliguria and generalized edema result from the reduced kidney function and fluid retention, while hematuria and proteinuria occur due to the increased permeability of the glomeruli that allows blood cells and proteins to pass into the urine.
