1. What term is used for the secretions of endocrine glands?
The secretions of endocrine glands are called hormones. These chemical messengers are released directly into the bloodstream and travel throughout the body to reach specific target organs or tissues. Unlike exocrine glands that release their secretions through ducts, endocrine glands are ductless and rely on the circulatory system to transport hormones to where they're needed.
Hormones regulate a wide range of bodily functions including growth, metabolism, reproduction, mood, and sleep cycles. Common examples include insulin from the pancreas, thyroxine from the thyroid gland, and adrenaline from the adrenal glands. The endocrine system works as a sophisticated communication network, ensuring that different organs coordinate their activities to maintain homeostasis and respond appropriately to internal and external changes.
