Study Notes
Tubular Reabsorption
- Tubular reabsorption involves the movement of substances from the glomerular filtrate back into the bloodstream.
- Primarily occurs in the renal tubule of the nephron.
- Essential for reclaiming valuable substances, such as glucose and amino acids, from the filtrate.
- Operates via peritubular capillaries surrounding the renal tubule.
Tubular Secretion
- Tubular secretion functions as the counterpart to tubular reabsorption.
- Involves the transfer of waste products from blood into the renal tubule.
- Aims to eliminate substances not adequately filtered during glomerular filtration.
- Plays a crucial role in maintaining the body's chemical balance by excreting excess ions and metabolite byproducts.
