Urine Formation: Glomerular Filtration or Ultrafiltration -

  • Kidneys filter 1100-1200 ml of blood per minute. 
  • The blood pressure in the capillaries of the glomerulus is higher than that of the afferent arteriole due to their narrow lumen.
  • This increased blood pressure results in the filtration of the blood across the semipermeable capillaries called ultrafiltration.
  • Water and many dissolved substances are filtered into the lumen of the Bowman’s capsule.
  • Blood cells and proteins are kept within the bloodstream by the filtration membrane.
  • The filtered components in the lumen of the Bowman’s capsule are collectively called the glomerular filtrate.
  • It consists of a large amount of water, urea, uric acid, creatinine, amino acids, glucose, sodium, potassium, vitamins, etc.
