英英释义

Butterflies in the stomach is the physical sensation in humans of a \"fluttery\"feeling in the stomach, caused by a reduction of blood flow to the organ. This is as a result of the release of adrenaline in the fight-or-flight response, which causes increased heart rate and blood pressure, consequently sending more blood to the muscles.
