Why are endocrine glands called ductless glands?
Answer and explanation
Correct answer: They release hormones directly into blood
The governing concept is the difference between endocrine and exocrine glands. Endocrine glands have no ducts or tubes for transporting their secretions. Instead, their hormones diffuse into nearby blood capillaries and are carried through the bloodstream to target tissues. Thus option A correctly explains the term ductless glands. Exocrine glands use ducts, while electrical message transmission is a function of nerve cells, not the defining feature of endocrine glands.
