उत्तर
- Renal cortex
-
- Afferent arteriole
- Glomerulus
- Bowman's capsule
- Efferent arteriole
- Ultrafiltration, tubular reabsorption, and tubular secretion.
- The process occurring in 2 and 3 is known as ultrafiltration.
Ultrafiltration: The blood flows through the glomerulus under great pressure, much greater than in the capillaries elsewhere. The reason for this greater pressure is that the efferent (outgoing) arteriole is narrower than the afferent (incoming) arteriole. This high pressure (hydrostatic pressure) causes the liquid part of the blood to filter out from the glomerulus into the renal tubule. This filtration under extraordinary force is called ultrafiltration.
