Introduction[edit | edit source]
Homeostasis, as defined thus "A self-regulating process by which biological systems maintain stability while adjusting to changing external conditions"[1]. Our bodies various functions must operate in a narrow range of balance internally, a dynamic equilibrium, in spite of a changing external environment. Our individual cells require our body to maintain these conditions to prevent the death of our cells, tissues and organs. [2]The body achieves this dynamic homeostasis by regulating temperature, glucose, toxins, blood pressure and pH.
Measures of homeostasis[edit | edit source]
Include:
- Our vital signs (blood pressure, core body temperature, heart rate, respiratory rate, and oxygen saturation) give an indication of a possible homeostatic imbalance.
- A basic metabolic panel can be done to show electrolyte disturbances.
When Homeostasis Fails[edit | edit source]
Homeostasis failure leads to many common disease processes. For example
- Diabetes
- Hypertension
- Fever
- With the normal aging process the body's ability to keep a steady homeostatis reduces, making older people more vunerable to disease. eg older people often find it harder to regulating their body temperature, they also have a harder time fighting infections and cancer.[3]
