ENDOCRINE HORMONES, YOU SHOULD KNOW THAT.

The Actions of Hormones -------------
The Hormones are natural chemical substances, that act after being secreted into the bloodstream from the ductless or endocrine glands.
Hormones have physiologic interrelationships. Hormones from various endocrine glands work in concert to obtain physiologic control of vital processes, their relationship is synergistic or antagonistic this allows for flexibility and control. Six major areas hormones play a crucial regulatory role: _______________________________________

(1) Control and coordination of the secretory motor activites of the digestive tract.

(2) Control of ENERGY PRODUCTION

(3) Control of coposition and volume of extracellular fluid.

(4) Adaptation, acclimatization and Immunity.

(5) Growth and Development.

(6). Reproduction and Lactation in women.

To maintain the internal environment ther must be control of hormone secretion, a hormone produces a physiologic effect. Increased hormonal secretions may be evoked in response to stimuli from the external environment: cessation of external stimuli terminates the internal secretion response.
Hormones are not "used up" in exerting their physiologic effects but must be inactivated or excreted if the internal environment is to be in dynamic equilibrium.


Note that the hypothalmus , it functions, effects behavior patterns, regulates the basic life functions of man ( control of water excretion, appetite, sleep - wake mechanisms, temperature, and blood pressure, has its relationships with other parts of the nervous system and endocrine system.


I am so very greatful to Louis Bartlo Re , Research chemist for providing me with this source book.
