Functions of the Endocrine System

Two systems regulate activity: the nervous system and the endocrine system

The endocrine system controls daily activity and long term changes such as development

What are glands?

Glands release chemicals into the blood stream.

(They are NOT like salivary or sweat glands, that deliver their chemicals through tubes)

What are hormones?

Hormones are chemical messengers made by endocrine glands.

Hormones turn on, turn off, speed up or slow down activities of a specific organ or tissue. Hormones act on target cells like a lock and key.

Hormones can work far from glands that make them since they are delivered by the bloodstream.

Hormones are slower but longer lasting than nerve impulse response.

Hormones act like a lock and key

What is the endocrine system?

The endocrine system is a complex group of glands.

Glands are organs that make hormones.

Hormones are substances that help to control activities in your body.

Different types of hormones control reproduction, metabolism (food burning and waste elimination), and growth and development. Hormones also control the way you respond to your surroundings, and they help to provide the proper amount of energy and nutrition your body needs to function.

The glands that make up the endocrine system include the thyroid, parathyroid, pancreas, ovaries, testes, adrenal, pituitary and hypothalamus.http://kidshealth.org/kid/htbw/_bfs_ESmoviesource.html
