Question

Quizplus · Accepted Answer

Loss of blood after an automobile trauma would activate the volumetric thirst system without directly affecting osmometric thirst. This is because the volumetric thirst system is triggered by a decrease in blood volume (hypovolemia), such as what occurs with significant blood loss, rather than changes in the osmolarity of the blood.
