What is the difference between hormones and glands?
The endocrine glands consist of: pineal; pituitary; thyroid and parathyroids; thymus; adrenals; pancreas; ovaries (female); and testes (male). Hormones are the chemical signaling molecules produced by the endocrine glands and secreted directly into the bloodstream.
Do endocrine glands only secrete hormones?
Major Endocrine Glands Not all organs that secrete hormones or hormonelike substances are considered part of the endocrine system. For example, the kidneys produce the hormone renin to help control blood pressure and the hormone erythropoietin to stimulate the bone marrow to produce red blood cells.
What gland does not produce hormones?
There is another type of gland called an exocrine gland (e.g. sweat glands, lymph nodes). These are not considered part of the endocrine system as they do not produce hormones and they release their product through a duct.
What are the major endocrine glands and their functions?
Endocrine system hormones
| Hormone | Secreting gland(s) | Function |

Which endocrine gland can you live without?
Adrenal Gland Essentials The adrenal medulla—the inner part of the gland—produces nonessential (that is, you don’t need them to live) hormones, such as adrenaline (which helps your body react to stress).
What happens when an endocrine secretion is too low?
This system affects growth and development, metabolism, sexual function, and mood. If your hormone levels are too high or too low, you may have an endocrine disease or disorder. Endocrine diseases and disorders also occur if your body does not respond to hormones the way it is supposed to.
