Answer:
Endorphins
Explanation:
Endorphins are neurotransmitters produced by the body in response to stress and pain. They act as natural painkillers and are released in situations of stress or injury, such as during an accident. Endorphins bind to the opioid receptors in the brain and spinal cord, reducing the perception of pain. This is part of the body's stress response to help the individual cope with the immediate danger or injury.
