Answer:
The correct answer is: Homeostasis.
Explanation:
Homeostasis is a key element in the correct functioning of the body, as it groups different processes that consist of regulating biological systems in order to maintain certain aspects of the body constant. If homeostasis were to fail, the body would sicken.
Homeostasis is controlled by two important systems: the nervous system, and the endocrine system. While they have many differences (for example, the nervous system's response is quicker and lasts less than the endocrine system's response), they share the capacity of sending messages to different parts of the body to generate responses that help us adapt to the varying conditions of the environment.
Examples of homeostasis include the regulation of body temperature, pH, and blood sugar levels (glycemia).
