Aldosterone
concerned with regulation of ionic balance
secreted by the cortex of adrenal glands
it increases sodium ion uptake by the gut and promotes the reabsorption of sodium ions (and therefore water) in the kidneys)
this is accompanied by elimination of potassium ions
this raises the overall level of sodium and lowers the overall level of potassium in the blood
as sodium ions are absorbed in the blood, chlorine ions follow so as to neutralize the effect of sodium ions
the production of aldosterone is regulated by the concentration of sodium ions which has an inhibiting effect, and a fall in sodium ions has a stimulating effect on the adrenal cortex
the ?ow of aldosterone is stimulated by the adreno-cortic-tropic hormone (ACTH) produced in the anterior of the pituitary gland however, the main method of control is dependent on the fact that adrenal cortex itself is somehow sensitive to the relative concentration of potassium and sodium in the blood
Adrenaline
produced by adrenal glands
in high concentrations, it increases hydrolysis of glycogen and increases blood sugar
it is usually released in emergency cases to increase glucose level for respiration
this releases energy for the emergency
