Verified step by step guidance

Understand the concept of tubular secretion: Tubular secretion is the process by which substances are transported from the blood into the tubular fluid. This process helps in the removal of waste products and the regulation of blood pH.

Identify the structures involved in tubular secretion: Tubular secretion primarily occurs in the proximal tubule, distal tubule, and collecting duct of the nephron.

Differentiate between the structures: The glomerular capsule is involved in filtration, not secretion. The nephron loop (loop of Henle) is primarily involved in reabsorption and concentration of urine, not secretion.

Evaluate the options given: Compare each option with the structures involved in tubular secretion. Eliminate options that include structures not involved in secretion, such as the glomerular capsule and nephron loop.

Select the correct answer: Based on the understanding of where tubular secretion occurs, choose the option that correctly lists the proximal tubule, distal tubule, and collecting duct as the sites of tubular secretion.
