16.6 role of the nephron in osmoregulation

Question 1

the nephron carries out its role in osmoregulation in the series of stages. these are

Answer 1

• the formation of glomerular filtrate by ultra filtration
• reabsorption of glucose and water by the proximal convulated tuble
• maintenance of a graidiant of sodium in the medulla by the loop of Henle
• reabsorobtion of water by the distal convoluted tubules and collecting ducts

Question 2

formation of glomerular filtrate by ultafiltration

Answer 2

• blood enters the kidney through the renal artery which branches into arterioles which enter a renal (bowmans) capsule of a nephron
• this is the afferent arteriole and divides to give the glomerular
• glomerulor capillaries later merge to form the efferent arteriole which subdivides into capillaries , which wind their way around
