Hormones circulate in the blood throughout the body. Why do they act only on certain organs?
Answer and explanation
Correct answer: Because target organs recognize specific hormones
Hormones are carried widely by the blood, but a response occurs only where cells possess the appropriate receptors. These receptors have a specific chemical shape and can recognize a particular hormone, so the organ becomes its target organ. Therefore option A is correct. Blood does reach many organs, hormones do not normally turn into bone, and the brain does not block all hormonal action.
