1. Nervous System: This system acts like the body's control center, receiving information from the environment and the body's internal state, processing it, and then sending out commands to muscles, glands, and other organs. It uses electrical signals and chemical messengers called neurotransmitters to communicate quickly and efficiently.
2. Endocrine System: This system uses hormones, which are chemical messengers produced by glands and released into the bloodstream. Hormones travel throughout the body, acting on target cells and influencing various bodily functions like growth, metabolism, mood, and reproduction. Their effects are slower and longer-lasting compared to the nervous system.
Both systems work together to maintain homeostasis (a stable internal environment) and coordinate complex processes within the body.
