The term is often used to refer to the body's tendency to monitor and maintain internal states such as temperature and energy levels at fairly constant and stable levels. This homeostatic harmony in … This naturally occurring phenomenon is the way nature works to ensure that balance stays in place. A Closer Look at Homeostasis Search. The body consists of trillions of cells that perform many different functions, but all of them require a similar internal environment with important variables kept within narrow ranges.
Learn how organisms maintain homeostasis, or a stable internal environment.
Homeostasis refers to the body's need to reach and maintain a certain state of equilibrium. Homeostasis & the Human Body - Chapter Summary. It is essential to keep the body in homeostasis to obtain and keep optimum health, mental clarity, stability, and bodily functions.
In general, homeostasis is essential for normal cell function, and overall balance. In the human body, chemicals like Oxygen (O 2), Carbon dioxide (CO 2) and digested food enter and exit the cells using the concept called diffusion and osmosis. Examples of homeostasis include the regulation of body temperature, and the balance between acidity and alkalinity. The lessons in this chapter will provide you with an in-depth overview of homeostasis in the human body. Search for courses, skills, and videos.

When the human body is maintained in a steady state, the condition is called homeostasis. Main content. The human body, for example, regulates its internal concentrations of hydrogen, calcium, potassium and sodium, charged particles that cells rely on for normal function. Homeostasis is defined as the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant.
