The body requires the constant and healthy environment that only homeostasis can provide Without this environment the body wouldnât be able to carry out the life support process.omeostasis is the maintenance of a constant environment in response to internal and external stimuli.
11. Homeostasis is the body process that attempts to maintain balance of internal environment variables such as pH, temperature, and blood sugar levels because cells and organs function properly in only a narrow range of conditions. 12.All cells have a cell membrane.he body attempts to maintain internal temperatures within this range though the process of homeostasis. However, in cases of exposure to extreme heat or cold, the homeostatic balance is disturbed, and cell die-off, organ damage, or even death can result. 2.
