Testis
heart
lung
liver
salivary gland

Key Takeaway: An endocrine gland is an organ that produces and secretes hormones into the blood stream. This is opposed to exocrine glands such as the salivary gland. The salivary gland secretes substances into ducts. The heart, liver, and lung are all essential to life processes, but none secrete hormones into the bloodstream.
