[Chapter 3, IX C; Table 3.6; Figure 3.21; Chapter 5 IV C 3 b (1)]. The decreased blood volume causes decreased renal perfusion pressure, which initiates a cascade of events, including increased renin secretion, increased circulating angiotensin II, increased aldosterone secretion, increased $\mathrm{Na}^{+}$reabsorption, and increased $\mathrm{K}^{+}$secretion by the renal tubule.
