Describe the importance of maintaining homeostasis, explaining why it is essential for cellular survival.
The environment of the cells in the body is threatened every minute by cellular activity and by the bodyfs own actions. ... This stability is known as homeostasis (Rutishauser, 1997).
Homeostasis is the physiological process by which the internal systems of the body (e. ... These internal systems and organs of the body contain millions of cells and these cells require relatively stable conditions to function effectively and contribute to the survival of the body as a whole (Tortora and Grabowski, 1996). To understand why homeostasis is essential for the survival of these cells, we first need to look at the immediate environment of the cell. ...
The regulation of the composition and volume of the internal environment (interstitial fluid + plasma) is vital in maintaining the consistency of another environment- the environment inside the cell itself. ...
Homeostasis is considered to represent a balance or equilibrium between these two processes (Clancy and McVicar, 2002). ... Thus, transport of materials across the plasma membrane between the extracellular fluid and the intracellular fluid is essential for cell survival, and the constituents in the extracellular fluid must be homeostatically maintained in order to support these life-sustaining changes (Sherwood, 1997).
Maintaining homeostasis.
Homeostasis refers to the maintenance of a dynamic steady state within the extracellular fluid that bathes every cell of the body. As these cells are not in direct contact with the external environment, cell survival depends on maintenance of a stable internal environment with which the cells can make exchanges. ... These are the systems that maintain homeostasis and to explain the principles of the process, we need to take a closer look at one of the bodyfs major systems (Clancy and McVicar, 2002; Sherwood, 1997).
The principles of homeostasis e. ... The function of the respiratory system is to provide this oxygen- obtained from the external environment- thereby maintaining the correct concentration levels of oxygen and carbon dioxide. ... By adjusting the rate at which the carbon dioxide is removed, the respiratory system is important in maintaining the correct pH of the extracellular fluid. ...
To look closer at how the respiratory system maintains the pH of the extracellular fluid, we must look at the control systems that operate to maintain homeostasis.
