Verified step by step guidance

Understand the process of urine formation, which involves several key steps: glomerular filtration, tubular reabsorption, tubular secretion, and excretion.

Identify the role of the glomerulus in the kidney. The glomerulus is a network of capillaries located at the beginning of a nephron, and it plays a crucial role in filtering blood.

Recognize that glomerular filtration is the first step in urine formation. During this process, the glomerulus filters blood, allowing water, ions, and small molecules to pass into the Bowman's capsule, forming the filtrate.

Differentiate glomerular filtration from other steps like tubular reabsorption, where useful substances are reabsorbed back into the blood, and tubular secretion, where additional waste products are added to the filtrate.

Conclude that the glomerulus is primarily involved in the glomerular filtration step, as it is responsible for the initial filtration of blood to form the filtrate.
