Final answer:
Homeostasis refers to the biological process in which the body maintains a stable internal environment, using negative feedback mechanisms to make adjustments in the face of internal and external changes.
Step-by-step explanation:
Homeostasis is the term which describes the process whereby the body maintains a constant internal environment. It involves continuous monitoring and adjustments to changes within the body to maintain equilibrium and ensure bodily functions remain within a certain range.
Human beings, for example, maintain stable internal body temperature. Systems within the body respond to changes by making appropriate adjustments. If the internal temperature rises, mechanisms such as sweating and increased blood flow to the skin help to cool the body. Similarly, if blood glucose levels increase, the body responds by releasing insulin to help distribute glucose to cells and lower blood concentration back to a normal level.
Negative feedback mechanisms play a crucial role in this process, acting to reverse changes and maintain balance. This dynamic equilibrium is essential for the proper functioning of cells and the overall health of an organism.
