Verified step by step guidance

Begin by understanding the structure and function of the nephron, which is the functional unit of the kidney responsible for filtering blood and forming urine.

Identify the key components of the nephron: the glomerulus, proximal convoluted tubule, loop of Henle, distal convoluted tubule, and collecting duct.

Recognize that the glomerulus is where blood filtration occurs, and the filtrate then moves into the proximal convoluted tubule for reabsorption of water, ions, and nutrients.

Understand that the loop of Henle is involved in concentrating the urine by reabsorbing water and salts, and the filtrate then moves to the distal convoluted tubule for further reabsorption and secretion.

Finally, note that the distal convoluted tubule is the last segment of the nephron before the tubular fluid enters the collecting duct, which is responsible for final adjustments to the urine composition before it is excreted.
