Final answer:
The flow of water in the renal tubule starts with filtration in the glomerulus and continues through the proximal convoluted tubule, loop of Henle, and distal convoluted tubule.
Step-by-step explanation:
The flow of water in the renal tubule starts with filtration in the glomerulus, followed by reabsorption and secretion in different segments of the tubule. The correct flow of water is a) Glomerulus, Proximal Convoluted Tubule, Loop of Henle, Distal Convoluted Tubule.
