Hormones are chemical messengers that coordinate different functions in your body. Several glands, organs and tissues make and release hormones, many of which make up your endocrine system.
Hormones are signaling molecules secreted by endocrine organs that regulate physiological processes in target cells. They control growth, development, metabolism, reproduction, mood, and homeostasis. Unlike neurotransmitters, hormones are secreted into the bloodstream and act at distant sites.
The endocrine system uses hormones to control and coordinate your body's internal metabolism (or homeostasis) energy level, reproduction, growth and development, and response to injury, stress, and environmental factors.
Hormones are chemical messengers in the body that glands form and release, or secrete, into the bloodstream, where they travel to various organs and tissues to change biological functions. Hormone levels fluctuate during a lifespan and even on a daily basis.
A hormone is an organic substance secreted by plants and animals that functions in the regulation of physiological activities and in maintaining homeostasis. Hormones carry out their functions by evoking responses from specific organs or tissues.
