Question

which of the following statements are true regarding endocrine glands? produce hormones produce enzymes are well - vascularized have ducts produce neurotransmitters

Explanation:

• Endocrine glands are ductless glands that secrete hormones directly into the bloodstream. They are well - vascularized to facilitate the transport of hormones. Enzymes are produced by exocrine glands (like salivary glands) or cells involved in digestion/metabolism, not endocrine glands. Ducts are a feature of exocrine glands. Neurotransmitters are produced by neurons, not endocrine glands.

Answer:

• Produce hormones
• Are well - vascularized
