Endocrine System

The endocrine system is a network of glands that secrete hormones into the bloodstream to regulate growth, development, metabolism, and reproductive processes. It works with the nervous system to transmit chemical messages throughout the body instead of using nerves. Some key glands include the pituitary gland, which releases hormones controlling other glands, the thyroid gland regulating metabolism, and the pancreas regulating blood sugar levels. Imbalances in hormone levels can impact the body's functions.

ENDOCRINE SYSTEM

 It is a network of glands across the body that secrete chemical messages called Hormones.
 The Endocrine System works alongside the nervous system. Instead of using nerves (sensory
and motor neurons) to transmit information, Endocrine System uses blood vessels (arteries,
veins and capillaries).
 Essential in regulating growth and development, metabolism, as well as reproductive
processes and mood.

Hormones – chemicals that are secreted into the bloodstream by endocrine glands.
– When hormones reach the target organ, it produces a notable effect.
– The word ‘hormone’ comes from the Greek work ‘hormao’ which means ‘excite’,
as hormones excite (stimulate) a particular part of the body.

Hormonal Imbalance – If the organ and hormones do not produce the regulated amount of
chemicals to your body.

Hypothalamus – the master switchboard. A part of the brain that controls the endo. system.
– It releases hormones to another part of your brain called the pituitary gland
