Verified step by step guidance

Step 1: Begin by understanding the structure and function of the renal tubules. The renal tubules are part of the nephron, the functional unit of the kidney, and are responsible for processes such as reabsorption and secretion.

Step 2: Clarify the processes that occur in the renal tubules. Reabsorption involves the movement of substances like glucose and water from the filtrate back into the blood. Secretion involves the active transport of certain ions and waste products from the blood into the filtrate.

Step 3: Identify the process that does not occur in the renal tubules. Filtration of blood plasma occurs in the glomerulus, which is part of the renal corpuscle, not the renal tubules. This is the initial step in urine formation where blood plasma is filtered to form the filtrate.

Step 4: Compare the listed functions to their respective locations in the nephron. Reabsorption of glucose and water, as well as secretion of ions, are functions of the renal tubules, while filtration of blood plasma is exclusive to the glomerulus.

Step 5: Conclude that the correct answer is 'filtration of blood plasma,' as it is not a function carried out in the renal tubules but rather in the glomerulus.
