Verified step by step guidance

Begin by understanding the structure of the nephron, which is the functional unit of the kidney. The nephron consists of several parts: the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Focus on the glomerulus, which is a network of capillaries located at the beginning of the nephron. It is surrounded by Bowman's capsule and is responsible for the filtration of blood.

Glomerular filtration is the process by which blood plasma is filtered through the walls of the glomerular capillaries into Bowman's capsule. This process is driven by blood pressure and involves the movement of water and solutes from the blood into the nephron.

Understand that the glomerulus is the primary site for glomerular filtration. It acts as a sieve, allowing water, ions, and small molecules to pass through while retaining larger molecules like proteins and blood cells.

Recognize that other parts of the nephron, such as the proximal convoluted tubule, loop of Henle, and distal convoluted tubule, are involved in reabsorption and secretion processes, but the initial filtration occurs at the glomerulus.
