They are the target organs. Hormones act on the target organs
They are called glands and they make up the endocrine system. Some glands are the hypothalamus, the pituitary gland, the thyroid and parathyroids, the adrenal glands, the pineal body and the ovaries and testes.

Secondary sexual characteristics. These are physical manifestations that develop during puberty, such as breast development in females, facial hair growth in males, and changes in body shape and voice pitch. These traits are not directly related to the reproductive organs but are influenced by sex hormones and indicate sexual maturity.
Synthesizing hormones refers to the process by which the body produces hormones in specific organs or glands such as the thyroid, adrenal glands, or pituitary gland. Hormones are chemical messengers that regulate various functions in the body, such as metabolism, growth, and mood. The synthesis of hormones involves a series of steps that convert precursors into active hormones that can then be released into the bloodstream to exert their effects on target organs.
Non-glandular organs are organs that do not produce or secrete hormones. They perform specific physiological functions in the body, such as digestion, filtration, and elimination of waste, but do not release hormones into the bloodstream. Examples include the heart, lungs, liver, and kidneys.
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.
Hormones
Because hormones have specific hormone binding sites to act
In men, the essential organs of reproduction are called the testes, which produce sperm and the hormone testosterone. In women, the essential organs of reproduction are called the ovaries, which produce eggs and the hormones estrogen and progesterone.
saliva and hormones
The chemical messages are called as hormones. They are released by the ductless endocrine glands into the bloodstream.
Immunology is the study of the body's defense system. Endocrinology is the study of hormones and endocrine 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.
The interior uterine lining is called the endometrium. The thickness of the endometrium varies throughout the menstrual cycle which is influenced by the hormones estrogen and progesterone.
