The adrenal medulla releases epinephrine and norepinephrine

which supplement the actions of the sympathetic nervous system on the heart and blood vessels.

7. The renin-angiotensin-aldosterone system is activated by the decrease in renal perfusion pressure. Because angiotensin II is a potent vasoconstrictor, it reinforces the stimulatory effect of the sympathetic nervous system on TPR. Aldosterone increases NaCl reabsorption in the kidney, increasing the circulating blood volume.

8. ADH is released when atrial receptors detect the decrease in blood volume. ADH causes both vasoconstriction and increased water reabsorption in the kidney, both of which will tend to increase blood pressure.
