Definition of Homeostasis

Inside the Human body there is a abundant of things happing. The body is a mechanical device and walking One way to define Homeostasis are associated and catagorized as an organism and a system which aids in maintaining within its parameters normal range of values. It is essential to life andany failures in homeostasis would most likely lead to diseases such as diabetes and hypertension.

Homeostasis is the primary concept in comprehending how the human body works. Homeostasis means keeping the cell or body at a normal and constant value, it means to maintain internal stability.

Homeostasis is occuring continuously in the human body. Because of Homeostasis, Humans are able to drink, eat, sleep, dance and sweat. the while the body anatomy stays almost exactly the same. Even if a person has a healthy or unhealthy diets or living a heathy or unhealthy lifestyle, the individual red blood cells, sodium, or level of glucose, sodium, red blood cells would exactly the same.

Because of Homeostasis, the body can drink and absorb gallons of water a day without swelling up like a balloon, and it doesn't shrink and shrivellike a dried prune when the body has been deprived of water. The human body is so remarkable that it knows how to preserve water and maintain a continuous level regardless of how much water an individual drinks, it also knows when it needs to store fluid when the body isn't getting enough water.

This maintenance of body size is an example of homeostasis. And we don't even have to think about it for this to happen! This describes how amazing the body really is.

There are so many other phenonmenal examples of how homeostasis works within the body. For instance, our concentration of salts and glucose is constant; our body temperature is usually around 98.6 degrees Fahrenheit; the amount of blood in our bodies is about 5 liters, the number of solutes of our blood remains about 300mOsm. The normal value of a physiological variable is called its set point.

How is Homeostasis Achieved?

The human body regulates several kinds of elements and it make up for changes in the human surroundings or environment. One amazing factor about the body is that it has thousands of sensors going off inside the body simultaneously and effectively. The sensors work together in monitoring the salt composition of blood, blood pressure, temperature, osmolarity, and many other features. The sensor detectors signal the control center and the brain whenever some value has deviated from its usual setting and activates compensatory modifications that will try to restore that value to normal.

For example, If a person was to step outside on a extremely hot day the temperature of there would begin to change. Inside of the human brain there is a temperature sensors which begins to rise from its set point, simultaneously initiating an effector tissue or organ that will aid in loweringthe temperature back to its original set point. For instance, whenever a person body temperature rises, almost immediately their body begins to secrete fluids better known as sweat. This is a compensatory response by the body to lower its temperature back to normal.

In the control room, the sensors and effector together form what is known as a control system. Control systems are everywhere; a thermostat that regulates room temperature is a classic example of a control system. Control systems that tend to reduce the difference between the desired value of a variable and the observed value are called negative feedback systems, or error correction systems.
