Which human organ produces hormones

Answer 1

Hormones are chemicals that carry messages from organs of the body to the cells. These messengers, then, regulate processes in the body (growth, reproduction, metabolism, digestion, balance between mineral and fluid, and the functioning of organs).

They are secreted, in animals, by organs, tissues, and glands, into the blood and carried to target organs. Once there, they may cause an alteration of the natural actions of the organ or a regulation of the production of other hormones.

Hormones can control behavior. There are two categories of hormones: peptides (they are short polymers formed from the linking, in a defined order, of α-amino acid) and lipids(lipids are a group of molecules which includes facts, waxes, sterols, fat-soluble vitamins, monoglycerides, diglycerides, phospholipids, etc. Their main biological funcions imply energy storage, as structural components of cell membranes and as important signaling molecules).

The endocrine system produces many hormones. The major endocrine glands are the pituitary, the thyroid and the parathyroid, the pancreas, adrenals, gonads. Hormones are secreted by the stomach, small intestine and kidneys, as well.

So, besides endocrine glands, there are cellular systems that can sinter substances with similar properties of hormones, for example, gastrointestinal hormones(gastrin, cholecystokinin, secretin, ghrelin, motilin, gastric inhibitory polypeptide, etc.)

I've added two links. Read as well, in the first link: "Advanced and supplemental topics related to gastrointestinal hormones".

Answer 2

Hormones travel through the blood so that would mean the heart causes hormones to move within animals/humans
