[VI C 4; IX C]. Angiotensin I and aldosterone are increased in response to a decrease in renal perfusion pressure. Angiotensinogen is the precursor for angiotensin I. Antidiuretic hormone ( $\mathrm{ADH})$ is released when atrial receptors detect a decrease in blood volume. Of these, only aldosterone increases $\mathrm{Na}^{+}$reabsorption. Atrial natriuretic peptide is released in response to an increase in atrial pressure, and an increase in its secretion would not be anticipated after blood loss.
