If an endocrine gland develops a duct and its secretion moves outside, why would its normal hormonal function be affected?
Answer and explanation
Correct answer: Hormones must enter the blood to reach their target organs
Endocrine glands are ductless glands. They release hormones directly into the bloodstream, which transports these chemical messengers to specific target organs. If a duct carried the secretion outside the body, much of the hormone would fail to enter the blood and would not reach its target in the required amount. Therefore option A is correct; the other statements do not describe endocrine function.
