It modifies these molecules and directs them to their appropriate destinations within the cell or for secretion outside the cell. This function is essential for maintaining the proper functioning of the cell and coordinating various cellular processes. Options A, C, and D are incorrect as they describe functions carried out by other cellular organelles, highlighting the specificity and importance of the Golgi apparatus in protein and lipid trafficking.

It consists of the renal corpuscle, including the glomerulus for filtration, and the renal tubule for reabsorption and secretion. The other options, such as the ureteric bud, renal pyramid, and glomerulus, are structures within the kidney but do not specifically refer to the filtering unit responsible for waste removal and blood volume regulation like the nephron does.
