Answer:
Homeostasis.
Explanation:
Homeostasis refers to any self-regulating process that living things use to actively maintain stability while adjusting to conditions (maintaining steady levels of temperature and other vital conditions such as the water, salt, sugar, protein, fat, calcium and oxygen contents of the blood) that are optimal for survival. We live a healthy life while homeostasis is successful, we get sick and it may lead to death when it is not successful. The term homeostasis was first used in 1930 by Dr. Walter Cannon.
