It actively monitors and regulates itself to remain nearly constant, or within narrow ranges in all aspects of its existence. It keeps its own temperature at between 36.4—37.2 ° Celsius. It keeps its blood saturated with oxygen between 95 and 100%. Blood pressure is kept between 60 and 80 diastolic and 90 and 120 mm Hg systolic. Heart rate at rest is between 60 and 100 beats per minute. The potassium concentration ranges between 3.5 and 5.0 mEq/l. One can go on, listing each aspect and area that the body is keeping afloat. Should these measurements stray much outside of these parameters, the body is in trouble, and unless corrected, sickness or death will soon follow.
This monitoring and regulating process is called homeostasis. Its concept was first described by French physiologist Claude Bernard in 1865, and the word was coined by Walter Bradford Cannon in 1926.
Homeostasis is a 24/7 365 process managed by the body’s 78 organs. (It actually may be 79. In November of last year, Professor J Calvin Coffey, of Limerick, Ireland, postulated strongly in the Lancet that the mesentery, a two walled membrane lining the abdomen, may be a fully independent body organ).
An organ is body tissues grouped together and joining each other to perform the duties and functions assigned by the body’s DNA. The organ’s main tissue is designed to do the specific function – for example the pancreas’s main tissue is designed to produce insulin—and the organ’s sporadic tissue is its blood and nerve supply, as well as the connective tissue that holds the organ together.
Our organs are arranged in systems, which are all closely connected and related. In total there are eleven organ systems in our body. I will list them in alphabetical order as there is not one of them that is not integral to homeostasis and life. They are the:
