Final answer:

The body prepares itself for the fight or flight response when experiencing heart palpitations, pupil dilation, and oxygenation of muscles due to stress or a perceived threat.

Step-by-step explanation:

The physical attributes of the heart beating faster, pupils dilating, and oxygen rushing to the muscle groups are all components of the body's response to prepare itself for the fight or flight response. When you encounter a potentially life-threatening situation, such as coming face to face with a bear while hiking, your sympathetic nervous system is activated, resulting in the release of hormones like epinephrine and norepinephrine. These hormones trigger a number of physiological changes that enable either combatting the threat or escaping to safety. This includes increased heart rate and respiration, dilation of the pupils and sweat glands becoming active, and the muscles becoming tense and ready for action.
