Hormones are organic chemical substances secreted by ductless glands (or endocrine glands) and are released into the blood stream for onward transportation to their target organs. Examples are: Pituitary, Thyroxin, Adrenalin, Insulin, Estrogens, progesterone, Testosterone, Para hormone, etc.The major endocrine glands include the two Adrenal glands, the Pituitary gland, the four Parathyroid glands, the Sex glands, and the Thyroid gland. A few hormones are produced by endocrine tissue present in organs that are not primarily endocrine glands. Such organs include the Brain, Stomach and Pancreas.Generally, hormones regulate a variety of body functions. They may be grouped according to the functions that they control. These functions include:- the way the body uses food; growth; sex and reproduction; the regulation of the composition of the blood; the body’s reaction to emergencies and the control of hormones themselves.
Human hormones are chemicals naturally secreted by your body. In proper balance they exert important effects on the finely tuned human organism. For example, hormones play a particularly vital role in helping the body to adjust to changes in its environment, which adjustment is often necessary for survival. Thus the body temperature of 98.6° F. must be held with but slight variations, and yet the temperature outside may vary as much as from 90 degrees below zero to 130 degrees above. Then again, strenuous labor creates so much heat that if the body did not have the means for cooling itself our muscles would literally cook. This sustaining of the body's internal balance in temperature despite changes in its environment is termed "homeostasis."
Among the various activities of the body that make homeostasis possible are those of the hormones, literally meaning "exciters" or "arousers." They are extremely powerful tiny bits of either simple or compound substances that accomplish their mission in quantities so small as to defy imagination. Just how small? Some hormone particles are so small that it would take three thousand million (3,000,000,000) of them to equal one ounce!
