Final answer:
Homeostasis is the process by which the body maintains a stable internal environment, ensuring that physiological processes function within a specific, optimal range despite external changes.
Step-by-step explanation:
When the internal environment of the body is functioning properly, a condition of homeostasis exists.Homeostasis is the process by which organisms maintain a relatively stable internal environment. In humans, equilibrium is achieved through various physiological processes that keep body conditions within specific limits. This balance is critical for proper functioning and involves maintaining temperature, pH, water levels, and other variables.
For example, despite external changes such as temperature fluctuations, humans maintain an internal temperature around 98.6°F. Homeostasis is achieved through negative feedback loops that act to counteract changes from the normal state. These adjustments are ongoing and dynamic, ensuring that each system operates within an optimal range.
