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
target cells
Hormones travel from endocrine glands through bloodstream to target organs.
Tropic derives from the suffix "-tropin" meaning stimulating, therefore tropic hormones stimulate their target organs to do something.
normone ,cgastrin which is produced by some cells of stomach
They are the target organs. Hormones act on the target organs
Hormones work by affecting Target Organs
hormones go to there target cells or target organs
target cells

Hormones travel from endocrine glands through bloodstream to 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 canβt 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.
target organs
Hormones are chemcial messengers released into the blood stream to be carried through out the body to target cells.

Tropic derives from the suffix "-tropin" meaning stimulating, therefore tropic hormones stimulate their target organs to do something.
