Question

Endocrine glands put their secretions directly into

• A. Ducts
• B. Blood
• C. Both
• D. None of the above

Answer 1

The correct option is B Blood

• Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct because endocrine glands lack ducts. Hence they are also called ductless glands.
• The major glands of the endocrine system include the pineal gland, pituitary gland, pancreas, ovaries, testes, thyroid gland, parathyroid gland, hypothalamus, and adrenal glands.
  
• Hence endocrine glands put their secretions directly into the blood.
• So, the correct answer is 'Blood'.
