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.

Are hormones transported throughout the whole body?
Yes, hormones are transported throughout the whole body via the bloodstream. They are produced by various glands and organs and travel to target cells or tissues to regulate various physiological functions.
How do circulating hormones differ from paracrines and autocrines with reference to their target cells?
Circulating hormones are secreted into the bloodstream and can affect target cells in distant parts of the body, whereas paracrines act on nearby cells and autocrines act on the same cell that produced them. Hormones travel through the bloodstream to reach their target cells, while paracrines and autocrines act locally without being transported through the bloodstream.
How do hormones reach the cells they affect?
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.)
Hormones affect specific tissues called?
Hormones affect specific tissues called target tissues or target cells. These tissues have receptors that bind to hormones, triggering a response or change in cellular activity.
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.

Yes, hormones are transported throughout the whole body via the bloodstream. They are produced by various glands and organs and travel to target cells or tissues to regulate various physiological functions.
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.
Chemicals that travel through the bloodstream and affect the activities of other cells?
Hormones

What hormones are able to travel through the bloodstream and affect cells throughout distant parts of the body?
Hormones such as cortisol, insulin, and adrenaline are able to travel through the bloodstream and affect cells throughout distant parts of the body. They are secreted by endocrine glands into the bloodstream and act on target cells with specific receptors, regulating various physiological processes.
Will gastric bypass affect your hormones?
Yes, gastric bypass affect your hormones such as those responsible for your body metabolism.
Why don't hormones affect all cells of the body?
Cause its hormones!
What are specialized cells in the brain that are able to travel through the bloodstream and affect cells throughout distant parts of the body?
Hormones
Are target tissues close to the glands that affect them?
most endocrine hormones are circulating hormones not local hormones.
What is the relationship between hormones and nutrition?
Hormones can affect nutrition by decreasing the appetite.
Is photosynthesis controlled by plant hormones?
No there is no affect. Direct affect is not known
What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs
