Final answer:
The two chemicals released during the fight-or-flight stress response that are associated with the development of heart disease are b) epinephrine and norepinephrine. They increase heart rate, breathing rate, muscle contractions, blood pressure, and blood glucose levels as a short-term stress response.
Step-by-step explanation:
The two chemicals released during the fight-or-flight stress response that are associated with the development of heart disease are epinephrine and norepinephrine. These hormones are released by the adrenal medulla and the nervous system, respectively, under extreme stress. They increase heart rate, breathing rate, muscle contractions, blood pressure, and blood glucose levels as a short-term stress response. Additionally, epinephrine and norepinephrine constrict the smooth muscles of the blood vessels, prioritizing blood supply to essential organs such as the heart, brain, and skeletal muscles.
