Answer :
The
hormones responsible for increasing sodium ion retention are angiotensin II and
aldosterone. Aldosterone
is the main mineralocorticoid hormone. It is a steroid hormone produced by the
zona glomerulosa of the adrenal cortex in the adrenal gland. It helps regulate sodium and potassium levels in the
body and also helps control blood pressure and the balance of fluids and
electrolytes in the blood. Angiotensin
on the other hand is a peptide hormone that causes a subsequent increase in
blood pressure and vasoconstriction. It is also part of the renin-angiotensin
system, which is a major target for drugs that raises blood pressure.
