Blood Volume Loss and Homeostasis

An illustration of blood volume loss and homeostasis explains how the body responds to bleeding or dehydration. It shows sensors detecting reduced volume or pressure, triggering responses such as increased heart rate, vasoconstriction, and hormone release. The diagram often includes the kidneys, heart, and blood vessels to show how systems work together to restore balance. This visual highlights how short-term and long-term mechanisms prevent shock and maintain circulation.
