What type of cells are hormones?
Hormones are not cells but chemicals released by cells to affect changes in other 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!
Why are hormones able to affect only certain cells and not other cells?
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
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.
Are hormones transported throughout the whole body?
Yes. Hormones are transported throughout the body, via the bloodstream. They do not, however, effect every cell. Only certain cells in the body have the proper receptor sites to accomodate hormones. Therefore, even though hormones are transported right through the body, they only create a reaction for certain things.
Which gland promotes development of certain lymphocytes?
Thymus gland does by secreting a group of hormones called thymosins, that affect production and differentiation of certain white blood cells which are T lymphocytes
What does the blood do in the cardiovascular system?
The blood in the cardiovascular system carries gases, hormones, nutrients, and wastes. Oxygen, nutrients, and certain hormones are carried to the cells; and carbon dioxide, wastes, and certain hormones are carried away from the cells. Hormones are not nutrients or wastes. They are chemical messengers that are secreted by certain cells and carried to other parts of the body where they will have an effect, which depends on the hormone.
Which hormone affect only certain cells?
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.
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.
What is a chemicals travel through the bloodstream and affect the activities of other cells?
I suppose that you think to oxygen.Oxygen is indispensable for life.
The signaling chemicals produced by one group of cells that affect distant target cells are called?
hormones.
