Chapter 16: Problem 1

What is Homeostasis?

Short Answer

Expert verified

Homeostasis is the process used by living organisms to maintain a stable internal environment, even in changing external conditions. Examples include regulating body temperature and controlling blood sugar levels. It plays a critical role in survival and functioning.

Step by step solution

Explanation of Homeostasis

Homeostasis is a term used in biology to describe the process that living organisms use to maintain a stable internal environment, despite changes in external conditions. It is derived from the Greek words, 'homeo,' meaning similar, and 'stasis,' which means stable.

Examples of Homeostasis

Here are some examples of homeostasis. In humans, homeostasis can be seen in the regulation of body temperature. On a hot day, the body sweats to cool down, while on a cold day, the body shivers to produce heat. This maintains a constant body temperature. There are also feedback mechanisms in the body that help maintain balance, like the secretion of insulin and glucagon to control blood sugar levels.

Importance of Homeostasis

The constant internal environment provided by homeostasis is critical for the survival and functioning of the organism. Without homeostasis, organisms might not adapt to environmental changes, leading to severe consequences such as illness or death. For instance, a sudden change in body temperature could cause hypothermia or heatstroke.
