Endocrine System In Human Body

Human is a complex structure as many biological systems make human and animal life possible. There are many vital systems in human body that perform function necessary for survival. Among the many systems in human body the endocrine system is of utmost importance. Endocrine system is the bodily mechanism which is responsible for the secretion of certain hormones through the involvement of glands. Endocrine glands are the primary part of endocrine system which are as; thyroid, pituitary, pancreas, adrenals, gonads and parathyroid.

However, majority of the tissues and organs are involved in the production of endocrine hormones. The endocrine system works by communication throughout the body and produces signals for the secretion of specific

The ability to function in organs and over a long distance in body is the primary reason why endocrine system is considered as endocrine system in body. As a result, endocrine glands can receive from one part of the body and bring changes over the other parts of the body making endocrine system as the most integrative system in human body. The ability to bring changes to nearby organs and distance organs is unique quality which is specific to endocrine system. Such integrative capacity has not been observed into other systems and organs of the body and this gives uniqueness to endocrine system. There are certain conditions to which when body is exposed then some changes are required and in order to do so, there should be certain mechanism to provide body with required substance in the required quantity. The hormones are secreted as the response to the conditions by the production of hormones which targets specific organs in order to induce certain changes (Hooper,

The word homeostasis is made up of two Greek words ‘homeo’ which means 'similar and the other is 'stasis, ' which means 'stable. The mechanism of homeostasis is function through variety of the means in order to keep changes of many kinds in body in stable condition. The regulatory mechanism of homeostasis tries to keep internal bodily conditions like P.H, temperature at a constant rate (Bray, 2016). It is a physiological mechanism which requires energy in order to perform its function in the body because constancy of internal environment is vital to life. The importance of homeostasis can be understood from the fact that if living body manages to regulate its internal changes and keep them in balance or at a constant rate, then there are chances for survival and continuation of life. But once if body is unable to do so, then the consequences will be damage to body even death is possible (Bray,
