Homeostasis is the scientific term for my body's ability to maintain its proper equilibrium temperature. Homeostasis refers to the body’s ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.). Homeostasis refers to the body’s ability to maintain a stable internal environment (regulating hormones, body temp., water balance, etc.). Homeostasis is also influenced by an organism's size, or more specifically, the surface-to-volume ratio. One of the most important examples of homeostasis is the regulation of body temperature. Cells need their environment to be just right in order for the cell to survive. From body temperature to blood pressure to levels of certain nutrients, each physiological condition has a particular set point. Homeostasis is the capacity of living organisms to maintain their internal stability of bodies, as appropriate to the temperature and pH (acidity and alkalinity balance), through the exchange of matter and energy with the environment.. c.

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. It is a dynamic process that requires constant monitoring of all systems in the body to detect changes, and mechanisms that react to those changes and restore stability. It’s perfect balance of all systems in your body — biological harmony and purity. This occurs thanks to various systems of metabolic self-regulation that sustain the dynamic balance necessary for the preservation of life.
