Kidneys continuously regulate
chemical composition of blood
Move passively down concentration grad
How molecules or ions move Water potential
Molecules move actively against concen
gradient
Maintain correct balance between water
Controlled by kidneys & skin
ADH Osmoregulation Vital to keep following constant
Greater solute concentration = greater
osmolarity & tendency fir water to move
osmosis
Antidiuretic hormone secreted by hypoth
What is ADH?
Stored in pituitary gland
, Steroid hormone produced by
adrenal glands
Control concentration of sodium
ions
Aldosterone
Too many sodium ions = high blood
pressure
Secretion trigger
sodium
Role of aldosterone
