Human physiology is dominated by homeostasis. Discuss this statement.

Homeostasis in a general sense refers to stability, balance or equilibrium. It is the body's attempt to maintain a constant internal environment. Maintaining a stable internal environment requires constant monitoring and adjustments as conditions change. This adjusting of physiological systems within the body is called homeostatic regulation.
Homeostatic regulation involves three parts or mechanisms: 1) the receptor, 2) the control center and 3) the effector.
The receptor receives information that something in the environment is changing. The control center or integration center receives and processes information from the receptor. And lastly, the effector responds to the commands of the control center by either opposing or enhancing the stimulus. This is an ongoing process that continually works to restore and maintain homeostasis. For example, in regulating body temperature there are temperature receptors in the skin, which communicate information to the brain, which is the control center, and the effector is our blood vessels and sweat glands in our skin.
Because the internal and external environment of the body are constantly changing and adjustments must be made continuously to stay at or near the set point, homeostasis can be thought of as a dynamic equilibrium.
To Start Physiology, Understand Homeostasis

Hemostasis the arest of bleeding from an injured blood vessel,requires the combined activity of vasculas,platelet,and plasma factors.
Regulatory mechanisms counterbalance the tendency of clots to form.
Hemostatic abnormalities can lead to excessive bleeding or to thrombosis.

Homeostasis a typically vital and broad topic in medicine or as DOCTOOR said, "To understand physiology understand homeostasis" .
Homeostasis is the normal functioning of the human systems which are built on inert mechanisms and any problem or up-normality that arise in it would be a pathological condition. Homeostasis is the way Allah made our body to function.
Homeostasis involve the control of our temperature, Body fluids concentration, plasma composition, Breathing and respiration, Hormonal communication, Neural and muscular signaling, Metabolism & many others that happen in our perfect body.
Imagine our body as a functioning system or a country (take it as a metaphor) the citizens or individuals of this country are the the different cells in our body, nervous system as the government of this country and Homeostasis as the rules and regulation the citizens should abide by not only that but also as the constitution of the country that monitors governments activities. any breach or malfunctioning of one sector of this system can lead to disastrous results to the whole parts and individuals of this system.
From here we can qoute a Hadith by mohamed (SCW) "The Mu'umins "Real believers" are like the human body that if one part of it is sick all the other parts would suffer with it by fever and amnesia"
From here you could understand how even the Rasul (scw) used this metaphor to demonstrate how interrelated a society could be.
In the conclusion of my short discussion I want to say "If there is something perfect it would be the physiology "Homeostasis" of the human body"
