- Definition: Glomerular Filtrate
- Definition: Selective Absorption
- Definition: Tubular Secretion
CISCE: Class 10
Definition: Ultrafiltration
Ultrafiltration is the process in which blood is filtered under high pressure in the glomerulus, allowing water and small solutes to pass into the Bowman’s capsule.
CISCE: Class 10
Definition: Glomerular Filtrate
Glomerular filtrate is the fluid formed after ultrafiltration that enters the renal tubule and contains water, urea, salts, glucose, and other small molecules.
CISCE: Class 10
Definition: Selective Absorption
Selective absorption is the process by which only useful substances like glucose, some salts, and water are absorbed from the renal tubule back into the blood, without disturbing its normal concentration.
CISCE: Class 10
Definition: Tubular Secretion
Tubular secretion is the active transfer of certain substances, such as ions and drugs, from the blood into the renal tubule during urine formation.
