The homeostasis regarding blood pH is called acid-base homeostasis where a proper equilibrium of acid and bases is reached in order to properly accomplish the normal cellular metabolism. On the other hand, the body temperature also is an example of homeostasis. For example, when our body temperature increases above the normal range, a negative loop will responsible to bring back the normal levels of temperature. Finally, the heart rate is also associated with homeostasis because the nervous system acts in order to send and receive signals in order to accomplish the demands of the body during a specific activity. So, water balance inside the body is not a good example. Of course, there are some mechanism that allow us to regulate this balance. However, this also depends on the electrolytes and water that we consume.

Homeostasis is the defined as the maintenance of an internal environment. A subset of this is Thermoregulation , which is the maintenance of body temperature. A reptile is an example of an Ectotherm , which means that its body temperature fluctuates with the external environment. Another way is the maintenance of water and salt levels in your body, which is known as Omsoregulation When body temperature increases, blood flow to the surface of our skin and we begin to Dilate...

The terms “equilibrium” and “homeostasis” refer to different things. Equilibrium plays an important role in the human body.
