What is the need for a system of control and coordination in an organism?

(N/A) The maintenance of body functions in response to changes in the environment by the integrated working of various body systems is known as coordination.
All movements that occur in response to stimuli are carefully coordinated and controlled.
In animals,control and coordination are provided by the nervous and muscular systems.
The nervous system sends messages to and from the brain,while the spinal cord plays a crucial role in relaying these signals.
Without a system of control and coordination,the body would not be able to function as a unified whole.
For example,when we accidentally touch a hot object,we immediately withdraw our hand due to a reflex action.
In the absence of this system,we would not perceive the danger or react,leading to severe injury or burns.
