There are hundreds if not thousands of hormones and each of them have effects on organs.
here are some of the basic ones
They are the target organs. Hormones act on the target organs
Hormones act at specific target organs because these organs contain specific receptors for the hormone. These receptors are typically proteins that bind to the hormone, leading to a biological response within the target organ. The presence of these receptors allows for precise signaling and control of physiological processes.
The hypothalamus regulates the release of hormones from the pituitary gland, not organs.
Not all organs are target organs for all hormones because hormones exert their effects by binding to specific receptors present on target cells. Each hormone has a unique structure that determines its compatibility with specific receptors, which are only found in certain tissues or organs. Additionally, the physiological role of a hormone dictates its action on particular organs, ensuring that hormonal signaling is precise and regulated, allowing for proper bodily functions and responses.
Hormones travel from endocrine glands through the bloodstream to reach target organs or tissues where they exert their specific effects. Some of the major endocrine glands that release hormones into the bloodstream include the pituitary gland, thyroid gland, adrenal glands, pancreas, and ovaries/testes.

hormones go to there target cells or target organs
Hormones affect specific tissues called target tissues or target cells. These tissues have receptors that bind to hormones, triggering a response or change in cellular activity.
Direct hormones act directly on target organs by binding to specific receptors on the cell surface, triggering a response within the cell. Tropic hormones, on the other hand, act indirectly by stimulating the release of other hormones from endocrine glands, which then affect the target organs.
Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.
Glands excrete hormones, which is sent to the blood which is then sent to the target organ.

The target organs of the pituitary gland include the thyroid gland, adrenal glands, gonads (testes or ovaries), and growth plates in bones. The pituitary gland releases hormones that stimulate these organs to produce their own hormones and perform specific functions in the body.
Cortisol has the broadest range of target organs among hormones. It affects almost every cell in the body and plays a vital role in various processes such as metabolism, immune response, and stress regulation.
