What is responsible for raising Jim’s heart and respiratory rate and stimulating sweat just before the race? Homeostasis is the cause. Jim is nervous but he is making his body be calm so he doesn’t psych himself out. His nervous system sends signals to his heart. His respiratory rate increases. Since his heart is beating faster and respiratory rate increased this caused him to breathe more rapidly and his
