Question

Which stage of the urine formation occurs under high pressure of blood?

• A. Ultrafiltration
• B. Reabsorption
• C. Absorption
• D. Adsorption

Answer 1

The correct option is A Ultrafiltration

Ultrafiltration takes place in Glomerulus of the Bowman's capsule of the nephron. The glomerulus consist of a tuft of capillaries, branched out of incoming or Afferent arteriole and outgoing Efferent arteriole

The diameter of the afferent arteriole is greater than that of the efferent arteriole and therefore blood flows under high pressure, where most of the substances and a large amount of water is filtered into the Bowman's capsule of the nephron, this filterate is called the ultrafiltrate and the process is called ultrafiltration

So, the correct answer is 'Ultrafiltration'
