Answer: The endocrine system plays an important role in homeostasis because hormones regulate the activity of body cells. The release of hormones into the blood is controlled by a stimulus. For example, the stimulus either causes an increase or a decrease in the amount of hormone secreted.
Hormones regulate the activity of body cells. It does this through releasing hormones in response to stimuli that give a positive and negative feedback loop.
For example: I am a fan of BTS. BTS makes songs on teenage mental health and how they can overcome it. When fans listen to their songs, they can relate because the lyrics are really meaningful; They feel 'safe' as they see their favourite artists as their source of hope.
