The Endocrine System Flashcards
is the collection of glands that produce hormones that regulate metabolism and growth and development among other things.
endocrine system
It uses chemical messengers (hormones) that are released into the blood to manage chemical processes of the body.
endocrine system
The 3 Main Functions of the Endocrine System
- Makes hormones that control your moods, growth and development, metabolism, organs, and reproduction.
- Controls how your hormones are released.
- Sends those hormones into your bloodstream so they can travel to other body parts.
are organs which produces and releases hormones that perform a specific function.
glands
There are 2 types of glands in our body.
endocrine and exocrine glands
they are ductless glands and release the substances that they make (hormones) directly into the bloodstream.
endocrine glands
Examples of Endocrine Glands
Anterior Pituitary
Thyroid
Adrenals
Parathyroids
They are glands with ducts. The secretions are delivered into ducts and end up on the epithelial surface.
Exocrine glands
Examples of Exocrine Glands
Salivary and sweat glands
are chemical substances secreted by endocrine cells into the extracellular fluids that regulate the metabolic activity of other cells in the body.
Hormones
Examples of Hormones
Insulin
Estrogen
Progesterone
Prolactin
Testosterone
Classification of Hormones
- Amino-acid based hormones
- Steroids
are relatively small molecules derived from the amino acids tyrosine and tryptophan.
Amino acid-based Hormones
Examples of amino acid-derived hormones
epinephrine and norepinephrine.
Made from cholesterol
steroid hormones
Includes sex hormones made by Gonads and the hormones produced by the adrenal cortex
steroid hormones
any of a group of hormones that belong to the class of chemical compounds known as steroids; they are secreted by three “steroid glands”
steroid hormones
what are the three steroid glands
the adrenal cortex, testes, and ovariesMajor Processes that Hormones Control
Major Processes that Hormones Control
- Reproduction
- Growth and development
- Mobilization of body defenses
- Maintenance of homeostasis
- Regulation of metabolism (the process by which the body changes food and drink into energy.)
Glands
- Hypothalamus
- Pituitary Gland
- Pineal Gland
- Thyroid Gland
- Parathyroid
- Thymus Gland
- Adrenal Gland
- Pancreas
- Gonads
It is responsible for maintaining your body’s internal balance, which is known as homeostasis.
Hypothalamus
the hypothalamus works with the _______ to control hormone production.
pituitary gland
It is a pea-sized gland that hangs by a stalk from the hypothalamus in the brain.
pituitary gland
Also called the Master Gland
