The answer is adrenal gland.

Hormones are chemical signaling molecules secreted by glands, either endocrine or exocrine. Endocrine glands secrete hormones directly into the bloodstream without using a duct, unlike the exocrine glands. Endocrine glands include pancreas, hypothalamus, pineal gland, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, ovaries, testes
