Whether the term “homeostasis” always indicates maintenance of internal constancy at the same level or there are various degrees of homeostasis and explain them with examples. Introduction: The term “homeostasis” indicates the maintenance of internal constancy at the same level. It is maintained by certain physiological processes. The term “homeo” indicates “similar” and “stasis” indicates “stable”.

The ability of the body to maintain internal stability is termed as homeostasis. In order to maintain homeostasis, the internal conditions should be monitored by the body. This occurs constantly in the body. In humans, there are various homeostatic processes such as temperature control, water as well as electrolyte balance, pH balance, respiration, and blood pressure maintenance.

One of the best examples is that the humans exhibit homeostasis that is of the rigid type in regard to the temperature of the body. When humans remain healthy without fever, the body temperature remains near 37˚C. Grant’s gazelle lives in an environment that is hot and dry. In gazelle’s hot habitat, the humans immediately start to sweat. The sweating helps to get free of high heat of the environment by keeping the body cool by maintaining the body temperature at 37˚C. As humans sweat nearly 2 liters of water per hour during the day time, the drinking water is very important...
