What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs
What are hormones transported to?
Hormones are transported to target cells, which are cells in another part of the body where the hormone will have an effect.
Hormones affect specific tissues called?
Hormones work by affecting Target Organs
Where do hormone go?
hormones go to there target cells or target organs
Hormones act at specific target organs because these organs contain what specific for the hormone?
target cells
Which of the hormones has the broadest range of target organs?
ACTH
How are hormones distributed through the body?
Proteins are transported through the blood stream.
What organs do hormones travel from endocrine glands through bloodstream?
Hormones travel from endocrine glands through bloodstream to target organs.
explain why hormones in the bloodstream are able only to affect target cells/organs and not other cells/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.
Most hormones are inactivated or excreted by what organs?
Glands excrete hormones, which is sent to the blood which is then sent to the target organ.
The hormones are carried by the blood of the circulatory system to the genetically conditioned?
target organs
What are hormones carried in to their target cell?
Hormones are chemcial messengers released into the blood stream to be carried through out the body to target cells.
