Coordination - GCSE Biology Definition

Coordination in biology refers to the way different parts of a living organism work together to respond to changes in the environment and maintain proper functioning. In humans and many animals, the nervous system and hormones play a key role in coordination. The nervous system uses nerve cells to quickly send messages to different parts of the body, while hormones are chemicals that travel through the blood to control and adjust bodily functions over a longer period. This teamwork helps organisms to react to external changes, such as temperature or danger, and also keeps internal processes like heartbeat and breathing steady, ensuring the body works smoothly as a whole.
