Endocrine glands. This is the basis of your endocrine system which secretes hormones into the blood stream directly without using ducts.
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 canโt 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.
Organs and glands secrete hormones, which means they release them into the bloodstream.
Proteins are transported through the blood stream.
Hormones work by affecting Target Organs
The endocrine system secretes hormones directly into the bloodstream. These hormones usually have target organs that they control. Hope this helps A RN in NJ
Hormones travel from endocrine glands through bloodstream to target organs.

They are the target organs. Hormones act on the target organs
Hormones are chemical messengers. They travel in your bloodstream to tissues and organs. They affect many different processes, including growth, development, metabolism, and reproduction. They are secreted directly into your bloodstream by endocrine glands, such as the pituitary, adrenal glands, pancreas, ovaries, and testes.
Proteins are transported through the blood stream.
Hormones work by affecting Target Organs
Hormones are the chemical messengers in the body that travel the bloodstream to the organs and tissues. They work slowly and affect many of the body's processes over time. Endocrine glands, which are special groups of cells, make hormones. Where physical changes such as growth etc. are the ultimate results of these hormones.
The chemical messages are called as hormones. They are released by the ductless endocrine glands into the bloodstream.
Because hormones have specific hormone binding sites to act
