Verified step by step guidance

Step 1: Begin by understanding the primary function of filtration in the excretory system. Filtration refers to the process of removing waste products and excess substances from the blood to form urine.

Step 2: Identify the structures listed in the problem: Glomerulus, Urinary bladder, Ureter, and Renal pelvis. Consider their roles in the excretory system.

Step 3: Recall that the glomerulus is a network of capillaries located within the nephron of the kidney. Its primary function is filtration, where blood plasma is filtered to form a filtrate that will eventually become urine.

Step 4: Contrast the glomerulus with the other structures: The urinary bladder stores urine, the ureter transports urine from the kidneys to the bladder, and the renal pelvis collects urine before it moves into the ureter. None of these structures are directly involved in filtration.

Step 5: Conclude that the glomerulus is the structure responsible for filtration in the excretory system, as it is specifically designed to filter blood and initiate urine formation.
