medulla
reabsorption of water
Cortex
ultrafiltration and selective reabsorption of blood contents
renal pelvis
collecting ducts
renal vein
filtered blood
renal artery
unfiltered bllood
ureter
carries urine to the bladder
Osmoconformers
maintain an internal condition that are equal to osmolarity of their environment
Problem in marine fish
They tend to lose water
They tend to gain ions
Osmoregulator
control internal osmolarity independent of that of the external environment
Problem in freshwater fish
They tend to lose ions
They tend to gain water
