Question

How does glomerular filtrate form?

Accepted Answer

- afferent arteriole is wider than efferent arteriole

- generates high hydrostatic pressure in glomerulus

- water and small molecules forced through

- pores between capillary endothelial cells,

- basement membrane, and

- pores between podocytes

- by ultrafilitration

- into Bowman's capsule

- proteins and RBCs are too large to pass through, so remain in capillaries
