What does communication happen within the body?

Communication within the body occurs through a complex network of signals between cells, tissues, and organs. This includes the nervous system, which transmits electrical signals via neurons, and the endocrine system, which releases hormones into the bloodstream. These systems work together to regulate bodily functions, respond to stimuli, and maintain homeostasis. Additionally, communication is facilitated by chemical signals, such as neurotransmitters and cytokines, that help coordinate responses at the cellular level.
