Homeostasis is the tendency within every living organism to maintain balance of its internal conditions in order to survive. Some examples of what our body regulates is hydration level, oxygen level, body temperature, blood pressure, and pH balance. The process of maintaining homeostasis comes from two different feedback loops, which are positive and negative feedback loops. A positive feedback loop brings a even greater change in the same direction, when the body senses a change (Raven). A negative feedback loop acts against the change sensed by the body, in order to retain the regular internal condition (Raven). One example for the process of retaining homeostasis is cellular respiration. Cellular respiration is the process in which a cell
