Question
Adrenaline reaches many organs in the blood. Explain why only some tissues respond strongly to it.
Answer
Only tissues with adrenaline receptors respond strongly. These receptors bind adrenaline and trigger a cell response; tissues without suitable receptors are exposed to the hormone but do not respond in the same way.
Explanation
This version applies the target-organ idea to a named hormone example, which makes it distinct from the definition-style question. It still stays inside the Human endocrine system subtopic: hormones are transported in blood, but the response depends on whether the target tissue has the correct receptor proteins.
Common mistake
Misunderstanding Target Organs
Students often think that hormones affect all tissues in the body equally, rather than specific target organs.
Emphasize that hormones are like keys that only fit specific locks (target organs), and review examples of hormones and their corresponding target organs to reinforce this concept.
