intercellular communication

Intercellular communication refers to how cells send and receive signals to coordinate functions within the body. They do this through chemical messengers like hormones or neurotransmitters that travel via the bloodstream or local areas. Cells have specific receptors that detect these signals, allowing them to respond appropriately—such as growing, dividing, or defending against infection. This communication ensures that different parts of the body work together harmoniously, maintaining health and responding to changes in the environment. Essentially, it's the body's way of cells talking to each other to keep everything functioning smoothly.
