Why do hormones affect only specific target organs?
Answer and explanation
Correct answer: Because target cells have specific receptors for them
The governing concept is receptor specificity. A hormone may circulate through the blood and reach many tissues, but it produces a response only where cells possess receptors with the appropriate shape and chemical compatibility. Therefore option B is correct. Hormones do not equally stop every organ, they are not restricted to the brain, and they are not immediately destroyed on entering the blood. Receptors determine the target-cell response.
