Verified step by step guidance

Step 1: Understand the structure of the nephron, which is the functional unit of the kidney. It consists of several parts, including the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Step 2: Learn the function of glomerular filtration. This process involves the movement of water and solutes from the blood into the nephron, forming the filtrate. It occurs in the glomerulus, a network of capillaries surrounded by Bowman's capsule.

Step 3: Differentiate the roles of other nephron structures. For example, the proximal convoluted tubule is responsible for reabsorption, the loop of Henle concentrates urine, and the collecting duct adjusts water and electrolyte balance.

Step 4: Recognize that glomerular filtration is the first step in urine formation and occurs specifically in the glomerulus, not in the loop of Henle, collecting duct, or proximal convoluted tubule.

Step 5: Confirm that the correct answer is 'Glomerulus,' as it is the site where filtration of blood plasma into the nephron begins.
