Filteration is flow of protien free plasma from glomerular capillaries into Bowmans capsule
Driving force-hydroststic pressure in glomerulus
Secretion-selective transfer of substances from blood into tubular fluid to rapidly eliminate them for body
Mechanism -active transport grin

how is PAH secreted:
a. active transport
b. passive transport
c. tertiary active transport

transport into the tubule cell across the basolateral memberane via tertiary active transport
transport from the cell into the tubule lumen via some form of carrier mediated passive transport
thats what i could find out!
