What system is responsible for the body's chemical communication through hormones?

The endocrine system is responsible for the body's chemical communication through hormones. It consists of glands that release hormones directly into the bloodstream. These hormones then travel to target organs or tissues, where they exert their effects on various physiological processes such as growth, metabolism, and mood regulation.

Hormones are crucial signaling molecules in the body, influencing processes over a longer duration compared to the rapid signaling of neurotransmitters in the nervous system. The endocrine system works in concert with the nervous system to maintain homeostasis and coordinate bodily functions, but its primary role is centered on hormone-based communication. This is in contrast to other systems, such as the immune system, which is focused on defending the body against pathogens, or the muscular system, which is primarily involved in movement and physical activity.
