Final answer:
The release of epinephrine and norepinephrine is primarily associated with the fight-or-flight response. These hormones increase energy levels, blood flow, and oxygen availability.
Step-by-step explanation:
The release of epinephrine and norepinephrine is primarily associated with the physiological response known as the fight-or-flight response. When a person is faced with a stressful situation, the sympathetic nervous system stimulates the release of these hormones, which provide a burst of energy to prepare the body to either fight or flee.
Epinephrine and norepinephrine increase blood glucose levels, stimulate the breakdown of glycogen to release glucose, and increase oxygen availability to cells by increasing the heart rate and dilating the bronchioles. These hormones also prioritize blood flow to essential organs while restricting blood flow to non-essential organs.
In summary, the release of epinephrine and norepinephrine during the stress response helps the body respond to danger by increasing energy levels, blood flow, and oxygen availability.
