Which of the following statements about the glomerular filtration is CORRECT ? I. The hydrostatic pressure of blood in glomerular capillaries allows filtration. II. The diameter of the efferent arteriole is lesser than the diameter of the afferent arteriole. III. The fluid collected in the urinary space contains all constitution of blood except RBCs. IV. The net filtration pressure at the glomerulus is around 40 mm Hg.

The correct match is I. DCT - Secretion of H^(+) and K^(+) ions II. Henle's loop -Reabsorption of glucose, water and Na^(+) ions III. Podocytes - Attached to parietal layer of Bowman's capsule IV. JGA - Rise in glomerular blood pressure activates it to release renin.
