what happens when the blood is processed at the renal arteries
the blood leaves the kidney via the renal veins and is transported in the inferior vena cave back to the heart
what are the 2 main functions of the kidney
excretion
osmoregualtion
what does excretion do
removes potentially toxic waste products made in cells during metabolism
what does osmoregulation do
the homeostatic control of body water by adjusting the solute conc of cells and body fluids. This ensures that cells do not burst which would affcet cell reactions
what does the ureter carry

what does the bladder store
urine prior to removal
where does kidney receive blood supply from
the renal artery
what does the kidney consist of
nephrons
