Verified step by step guidance

Step 1: Begin by understanding the nephron's role in the kidney. The nephron is the functional unit of the kidney responsible for filtering blood and forming urine.

Step 2: Identify the structures listed in the problem: Distal convoluted tubule, Glomerulus, Loop of Henle, and Collecting duct. Each has a specific function in the nephron.

Step 3: Focus on the filtration process. Filtration occurs when blood plasma and solutes are filtered out of the blood into the nephron. This process happens in the renal corpuscle, which includes the glomerulus and Bowman's capsule.

Step 4: Understand the glomerulus's role. The glomerulus is a network of capillaries where blood pressure forces water, ions, and small molecules out of the blood and into Bowman's capsule, initiating urine formation.

Step 5: Compare the functions of the other structures. The distal convoluted tubule is involved in secretion and reabsorption, the Loop of Henle concentrates urine, and the collecting duct transports urine to the renal pelvis. None of these are primarily responsible for filtration like the glomerulus.
