Question

what is ultrafilteration and how does it occur?​

Answer 1

Answer:

The blood flows through the glomerulus under great pressure which is much greater than in the capillaries elsewhere. the reason for this greater pressure is that the efferent arteriole is narrower than the efferent arteriole.this high 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.
