What is Homeostasis?

Homeostasis is all about keeping a steady balance in the internal environment. This balance has to be at an optimum range of level as temperature, respiration which is carbon dioxide and oxygen, blood glucose and blood pressure and pulse.  The human body needs to have a balance of everything by regulation. The internal environment is the conditions inside the human body. The conditions stay mostly constant despite any changes in the outside environment such as temperature. The skin, kidneys, liver, endocrine system, nervous system and sensory system each play a part in retaining the internal environment. The external temperature can change depending on each day and the season we are in. The temperature could be 40 degrees; however, the human body temperature would stay the same which is about 37 degrees.  By sweating, vasodilatation, vasoconstriction and shivering the humans body temperature stays the same. When people exercise, temperature of the body will rise; the sweat glands are then activated and secrete sweat onto the skin. When the sweat is then evaporated then heat is taken from the body and the temperature of the body decreases.

The things inside the human body which need to be kept the same are:

Carbon Dioxide: any carbon dioxide in the body which is extra needs to be removed because if not then the body will become acidic. Carbon dioxide is breathed out in the air.

Urea: The urea is a waste chemical that is made when we digest amino acids in the liver. This chemical is poisonous therefore, must be removed. It will be removed through urinating and through sweating.

Ions: Ions are atoms and they have extra electrons or missing electrons.  If the ions inside ...
