Why is homeostasis so important???

Homeostasis is important because without restoring balance after a stimulus causes change in the body, the body would go through extreme changes that could possibly be fatal. For example, in the "What's Your Temperature Now" lab, the body responded to the hands exposure to the ice water for 30 seconds by the surface temperature of the hand increasing to prevent hypothermia. At the same time, the core temperature of the body increased as well in order to preserve the vital organs like the heart, brain, and lungs by increasing blood flow to these organs. Another example of the importance of homeostasis can be seen in the "Stepping up the Pace Lab" when the respiratory, circulatory, endocrine, and nervous system all worked together in order to restore balance during and after exercising. The level of carbonic acid in the blood rose and was sensed by the brain and aorta, issuing a response of increased breathing and heart rate which removed the excess carbon dioxide and brought in more oxygen to properly oxygenate the cells. Although not seen in this specific test, if the intensity of line jumps was increased and done for a longer period of time, the test subject would also perspire in order to try and maintain temperature balance.n
