Final answer:
Hormones are chemical messengers released by endocrine glands that help maintain homeostasis by regulating the functions of other cells throughout the body.
Step-by-step explanation:
Chemical messengers released by endocrine glands to regulate some functions of other cells are known as hormones. These chemical-signaling molecules are essential for maintaining homeostasis within the body by coordinating different systems and organs. They are secreted into body fluids, such as blood, and travel to various parts of the body to reach their target cells, which have specific receptors for these hormones. Endocrine glands like the pancreas, adrenal glands, and thyroid gland produce various hormones which play roles in regulating blood-glucose levels, stress responses, and metabolic rates, respectively. Unlike neurotransmitters, which have localized effects, the effects of hormones are more widespread, and they generally work over a longer period.
