tubular reabsorption
Kidney reclaims filtrate
Tubular reabsorption is the process by which the kidney reclaims useful substances from filtered fluid and returns them to the bloodstream.
As fluid passes through the tubules of the nephron, water, glucose, amino acids, and electrolytes are selectively reabsorbed rather than lost in urine.
The process is essential for maintaining the body's fluid balance and conserving nutrients.
