The human body needs to maintain stable internal conditions and characteristics such as blood glucose level, calcium concentration, optimal temperature, water content, etc. This tendency to go to a state of equilibrium among variables, conditions and functions of the body is referred to as ___(1)____. In order to maintain it, systems in the body employ ____(2)_____ which dictates the increase or decrease of the level or amount of a condition or variable. For example, when theincreased amount of a hormone triggers the production of a second hormone, it is called a ____(3)_____ feedback mechanism. Sometimes, the increased amount of a variable decreases or stops the production of a hormone. In this case, it is considered a ____(4)____ feedback mechanism.Two different hormones can be used to maintain homeostasis of a single variable. For example, the hormone ___(5)____ is used to store excess glucose from the blood into the liver and muscles as glycogen. The hormone ____(6)____ does the reverse which is to covert back the glycogen in the liver and muscles to blood glucose.The hormone ___(7)___ is used to store calcium in the bones while the hormone __(8)___ triggers the release of calcium from the bones.Maintaining homeostasis requires the coordinated functions of different systems.
