The traditional approach is that human and animal hormones are produced in endocrine glands, which release them directly into blood, and the bloodstream carries them to their target cells. However, it doesn't necessarily have to be blood, it can be tissue fluid as well. (And not all organisms that have hormones have blood either. In plants for example, hormones can migrate to other cells from the site of production through the plasmodesmata that connect neighboring cells.)

The endocrine system releases hormones into the bloodstream, which carries the chemical messengers to throughout the body where they eventually bind with receptors on their target cell or tissue.

Hormones are usually transported through and affect only cells with?
Local hormones are usually transported through cells and only affect the cells that are in that locality. They have the ability to affect all cells that they come into close contact with.
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.
How do hormones leave the cell?
Most hormones reach target cells by blood . Some types of hormones reach target cells by other ways e.g. pheromones via air ; local hormones via diffusion etc .
How does protein hormones reach their target cells?
Usually in blood plasma, which carries them to their target cells. They 'recognize' these cells based on receptors on the cell membranes to which they bind.
How do hormones travel to their targets in animal cells and in plant cells.?
The process is different for plants and animals. In animals, the hormones are transported by the circulatory system, which eventually allows them to reach the target cells with appropriate receptors. In plants, the hormones are signal molecules, and they're not produced in large concentrations; they regulate targeted cellular processes in the plant that produces them.
What type of cells are hormones?
Hormones are not cells but chemicals released by cells to affect changes in other cells.
How do endocrine glands communicate with cells?
endocrine glands secrete hormones into the bloodstream and these hormones reach cells and impact these cells.
Hormones are usually transported through and affect only cells with?
Local hormones are usually transported through cells and only affect the cells that are in that locality. They have the ability to affect all cells that they come into close contact with.
Why don't hormones affect all cells of the body?
Cause its hormones!
Is it possible to see hormones?
Hormones are chemicals released by cells, which then affect other cells in the body. No, they cannot be seen, as they are chemicals.
