Which statement correctly defines an endocrine gland?
Answer and explanation
Correct answer: It releases hormones directly into the blood

The blood transports these hormones to particular target organs or cells. Therefore option A is correct. Option B describes duct-based exocrine secretion, while options C and D refer neither to the definition nor the function of an endocrine gland.
