What is the primary function of endocrine glands?

• A. Release hormones into the bloodstream
• B. Release digestive enzymes into the stomach
• C. Produce neurotransmitters
• D. Store hormones

Answer: (A)

Endocrine glands release hormones into the bloodstream, and these chemical messengers travel to distant targets to regulate processes like metabolism, growth, and stress responses. Hormones bind to specific receptors on target cells, eliciting appropriate physiological actions that help keep the body in balance. This differs from exocrine secretions, which are released into ducts to reach a specific site, such as digestive enzymes into the stomach. Storing hormones isn’t the primary role of these glands, and neurotransmitters are produced by neurons rather than endocrine glands.
