The loss of 0.5 L of sweat would stimulate a greater increase in vasopressin secretion than the loss of an equal amount of blood plasma over the same period of time. This statement is:

Quizplus · Accepted Answer

Sweat is hypoosmotic to plasma, meaning that it has a lower concentration of solutes than plasma. Therefore, the loss of sweat would dilute the remaining plasma, leading to a decrease in vasopressin secretion. On the other hand, the loss of an equal amount of blood plasma would not change the osmolarity of the remaining plasma, so vasopressin secretion would not be affected as greatly. Therefore, the statement is false, and choice B is the correct answer.

The Loss of 0
