Describe when inflammation is good and when it is bad
Barbie and Ken, both 17 years old, had been going out for a year. They went everywhere together, including dances, baseball games, and family gatherings. They ate lunch together and did their homework together. One day, for no apparent reason, Barbie ghosted Ken! It was clear she did not want to see him anymore . Ken was shocked, dismayed and devastated all at once. He continued to feel the effects of this break up for quite some time. Concentrating on secretions from the adrenal gland and the feedback mechanisms involved, describe in detail Ken's response to this stress.
