Question

Main functions, of kidney is

• A. Passive absorption
• B. Ultrafiltration
• C. Selective reabsorption
• D. Both B and C

Answer 1

The correct option is D Both B and C

Glomerular blood is filtered through filtration slits present in Bowman's capsule. The Bowman's capsule collects the filtrate and it enters the tubules of the nephron. Glomerular filtration is also called as ultrafiltration because filtrate consists of almost all constituents of plasma except proteins. Selective reabsorption occurs in the proximal convoluted part of nephron through which important constituents of blood filtered along with nitrogenous waste are selectively reabsorbed

So, the correct answer is 'Both B and C'.
