Question

Choose the correct statement regarding urine formation.

• A. Filtration is non-selective process performed by glomerulus.
• B. The glomerulur capillary blood pressure causes filtration of blood through three layers
• C. GFR in a healthy individual is approximately 125 mL/ min
• D. A fall in GFR activates the JG cells to release renin.
• E. The ascending limb of the Henle's loop is permeable to water but allows transport of electrolytes actively and passively.

Answer 1

Answer: (E)

Ascending limb of loop of Henle is impermeable to water. Here water is not reabsorbed, rather sodium, potassium, magnesium and chloride are reabsorbed and therefore the filtrate becomes hypotonic to blood plasma
