answered-by-expert Expert Answer
Ultrafiltration:
  • The efferent arteriole is narrower than the afferent arteriole which develops a build hydrostatic pressure on the blood.
  • Thus, the blood flows through the glomerulus with great pressure.
  • Due to the pressure, the liquid part of the blood which filters out from the glomerulus passes into the Bowman’s capsule.
  • This filtration under extraordinary force is called ultrafiltration.
  • This filtrate is known as the glomerular filtrate.
  • The glomerular filtrate consists of water, urea, salts, glucose and other plasma solutes.
  • Blood corpuscles, proteins, and other large molecules remain behind in the glomerulus. Therefore, the blood carried away by the efferent arteriole is relatively thick.
