What type of cells are hormones?
Hormones are not cells but chemicals released by cells to affect changes in other cells.
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.
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.
The endocrine system produces chemicals that affect organ functions these chemicals are called?
The chemicals produced by the endocrine system that affect organ functions are called hormones. They act as chemical messengers, signaling specific cells to perform certain functions in the body.
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.
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.
The signaling chemicals produced by one group of cells that affect distant target cells are called?
hormones.
Chemicals that travel through the bloodstream and affect the activities of other cells?
Hormones
Hormones are usually transported through and affect only cells with?
specific hormone receptors on their surface, allowing for targeted signaling. This ensures that hormones act only on cells that are equipped to respond to their specific signals, optimizing the cellular response to hormonal stimuli and maintaining proper physiological balance.
What chemical messenger has specific regulatory effects on certain cells?
Hormones and neurotransmitters
