Hormones
Hormones are chemical substances secreted by endocrine glands. They are secreted in small quantities directly into the bloodstream. Usually, hormones are secreted in one place but used in places far from their origin. Although hormones are carried by the blood to all parts of the body, only targeted tissues or organs will respond to them.

The roles played by hormones are: a) increasing or decreasing the rate of body process and an example is increasing the rate of heartbeat b) causing physical and physiological changes in the body c) influencing body growth. Excessive or insufficient amounts of specific hormones have undesirable effects on the health of an individual. Examples of hormones are thyroxin adrenaline, oestrogen, testosterone and insulin.
