Question

In the Heart Rate Lab you designed, you were able to see that when your body releases adrenaline or has other emotional or physical responses to stimuli, your heart rate increases in an attempt to pump more oxygen to your cells to keep your body in balance.

Please describe one other example in your body of a system that is trying to stay balanced or works to maintain homeostasis.

Answer 1

When your body gets overheated. This is a negative feedback loop. The arteries/veins will dilate letting more blood pass through. Your face tends to get red because there is more blood flow towards the surface in an effort to cool off. This is also why you sweat.
