The graph below has had its labels removed. One axis is plasma osmolarity. The other axis is EITHER plasma vasopressin concentration OR plasma aldosterone concentration. Write the correct label on each axis of the graph, and explain how you came to that conclusion.
The dependent variable is typically used for the y-axis, and the independent variable for the x-axis. Plasma osmolarity is the independent variable, and it regulates the secretion of hormones. As osmolarity increases, vasopressin secretion increases to promote water retention, but aldosterone secretion is inhibited to promote sodium loss. Therefore vasopressin concentration is the correct label for the y-axis. See Figure 20.6 in the chapter.
