The general properties of hormones are
1. Hormones are secreted from their source (an endocrine glad) directly into the blood.
2. They regulate the physiological processes by chemical means. They affect the enzyme systems of the body.
3. They act on target organs or cells usually away from the source.
4. Hormones produced in one species usually show similar influence in other species.
5. They are produced in very small quantities and are biologically very active.
6. Chemically, some hormones are peptides, amines or steroids.
7. Their excess (hypersecretion) or deficiency (hyposecretion), both may lead to serious consequences.
8. Hormones are not stored in the body and are excreted from the body.
