The hypothalamus regulates many hormonal functions. The lungs improve the gaseous exchange within the alveolus helping the intake of oxygen and expulsion of carbon dioxide which is by diffusion. The liver balances the blood glucose concentrations maintaining the correct levels. The role of the skin is in making sure that the body temperature does not deviate too much beyond accepted limits. Reflexology has a wonderful way of helping balance all the above systems of the body and all secretory functions.
Secretion is one of the skin's most important functions.
It is essential that the correct balance is maintained. The pH of the skin is most important, just like the pH of the body fluids, all of which must be maintained at a neutral pH level. The sweat glands are governed by the sympathetic nervous system. Often when there is excess stress or an emotional overload, activity within the glands increases and they discharge cellular matter as well as fluid. Eccrine sweat is a slightly acid and watery fluid which contains and excretes a certain amount of urea, one of the chief waste products of the body.
