Glomerular filtration occurs by active transport of Na⁺, which then creates an osmotic gradient for the filtration of water.

Question

Quizplus · Accepted Answer

Glomerular filtration occurs by passive filtration of water and small solutes through the glomerular capillaries into Bowman's capsule. Na⁺ is reabsorbed in the proximal tubules and its active transport does not play a role in the initial filtration process.
