In addition to controlling blushing, it also tells our heart to beat and our lungs to breathe. A stressor is something that causes stress. When we face a stressor, the involuntary nervous system releases a special chemical. It's called adrenaline. When the body senses this chemical, it responds in several ways. Our heartbeat speeds up.
