The tubular fluid is isotonic as it enters Bowman's capsule because it is the same composition as blood plasma. It remains isotonic at the beginning of the loop of Henle because no solutes have been removed yet. It becomes hypertonic at the tip of the loop of Henle because water has been reabsorbed, creating a higher concentration of solutes in the remaining fluid. Finally, the fluid becomes hypotonic as it leaves the loop to enter the distal tubule because most of the solutes have been reabsorbed, leaving behind mostly water.
