Animals, such as squirrels, prepare for activities like fighting or running away through the release of the hormone adrenaline from the adrenal glands, facilitating widespread changes in various tissues to conserve energy and coordinate responses.

Animals, such as squirrels, prepare for fight-or-flight responses in scary situations through the activation of their sympathetic nervous system. This triggers the release of stress hormones like adrenaline, initiating physiological changes. Heart rate and blood pressure increase to enhance oxygen delivery, while blood is redirected to vital organs. Squirrels exhibit heightened alertness, dilated pupils, and increased energy metabolism. Additionally, they may engage in behaviors like freezing, assessing the threat, or displaying defensive postures. These adaptive responses optimize their chances of survival by either confronting or escaping from potential dangers in their environment.
