← Human Body & HealthWhich consequence results when tubular flow exceeds transport maximum?
A)Increased solute excretion occurs✓
B)Enhanced water reabsorption happens
C)Reduced plasma osmolarity develops
D)Increased ADH secretion occurs
💡 Explanation
Increased solute excretion occurs because the countercurrent multiplier mechanism is overwhelmed, therefore solutes bypass reabsorption in the loop. Rather than reabsorbing everything, increased flow saturates transporters, reducing osmolality gradient effects.
