Question

Read the following statements and find out the INCORRECT statement.

$(a)$ During urine formation, the tubular cells secrete substance like $H^{+}, N a^{+}$ and $H C O_{3}^{-}$ into the filtrate.

$(b)$ As glomerular filtrate move down in descending limb of henle it gets concentrated and as concentrated filtrate pass upward in ascending limb of HL it gets diluted.

$(c)$ Conditional reabsorption of $N a^{+}$ and water takes place in PCT.

$(d)$ Reabsorption in ascending limb of HL is minimum.

TestHub · Accepted Answer

Urine formation involves Ultrafiltration, Selective reabsorption and Tubular secretion. Henle's loop consists of descending and ascending limbs. Descending limb absorbs water and thus filtrate gets concentrated while ascending limb absorbs sodium and thus filtrate gets diluted. Reabsorption of sodium and water takes place in distal convulated tubules as ADH acts on it. The substances that are secreted from tubular cells are Hydrogen, ammonia and potassium.
