The answer is "Physiological arousal".

Arousal begins in the cerebrum, where the Reticular Activation System interfaces the crude mind stem and the cortex and influences dozing waking advances. In arousal, it acting to build our attentiveness and resulting readiness and consideration. In excitement caused by a danger, the fight-or-flight response is activated.  

The endocrine framework stimulates different organs, specifically adrenaline, which expands oxygen and glucose stream, widens the understudies (so you can see better) and smothers non-pressing frameworks, for example, digestion and the immune system.

Arousal is spread through the Sympathetic Nervous System, with impacts, for example, expanding the pulse and breathing to empower physical activity and sweat to cool the body. It likewise has particular activities, for example, stimulating sexual arousal.
