Answer:
It processes the environment and sends out signals.
Explanation:
Sense receptors can sense any changes in internal or external conditions which disturb the homeostasis. The sensory information is sent to the central nervous system which in turn process the information and commands the respective body parts to perform actions to restore the homeostasis.
Example: The information about increased demand of oxygen during exercise is sent to the brain which in turn commands parts of breathing system and cardiovascular system to increase the breathing rate and heartbeat rate respectively to compensate for increased oxygen supply.

Jump-start algorithm are generally used to sort children into categories based on the degree or extent of the injuries in multiple -causality situations.
it is applicable to children from infancy to age 8yrs,
It is divided into 4-categories called Triage categories,with certain 4- colors where each indicates the extent of severity of the child conditions represented with tags.
Thus Red- tag indicated need for urgent medical attention,because of life threatening injuries.
Yellow indicated although medical attention is needed, the injury is not life threatening. Intervention may be delayed for few hours.
Green-indicated minor injury, that is not so serious,medical intervention may be delayed for some days
Black indicated diseased or the injury is so severe that the life of the victim can not be saved with available resources.
