Final answer:
Pain is discomfort resulting from tissue damage or exposure to noxious stimuli. It is part of the somatosensation group and helps us become aware of injuries and motivates us to remove ourselves from the cause.
Step-by-step explanation:
Pain can be defined as discomfort resulting from tissue damage or exposure to noxious stimuli. It is caused by true sources of injury, such as contact with a heat source that causes a thermal burn or contact with a corrosive chemical.
