Why can hormones act on organs located far away in the body?
Answer and explanation
Correct answer: Because they travel with the blood
The governing concept is endocrine transport through the circulatory system. An endocrine gland releases its hormone into the blood rather than sending it through a duct or a single nerve. Since blood circulates throughout the body, the hormone can be carried to distant tissues. Only cells with suitable receptors respond strongly to it. Thus A is correct; B and D describe restricted locations, while C confuses hormones with nerve impulses.
