SUMMARY: Homeostasis Sprint Challenge is a collection of mini games that shows how the body responds during a sprint. you will complete different challenges to help the runner keep moving, stay protected, and maintain balance inside the body. INSTRUCTIONS: KEYS:(not all keys apply to every game) [SPACE] to boost [G] to breathe [P] to exhale [MOUSE] to point in direction
Welcome to the Homeostasis Sprint Challenge! ____________________________________________ In this game, you'll finish five mini-games showing how various body systems assist you while sprinting. Though each system has its own specific task, together they help provide energy, manage movement, safeguard the body, and keep homeostasis. NERVOUS SYSTEM First, in the nervous-system mini-game, you send a nerve signal from the brain to the leg muscles. When it gets there, it tells the muscles to contract. This lets your runner move their legs and keeps sprinting. remember that the signal transfers down the neuron's axon. Dendrites get the signal from other cells, and then the axon carries it on to the muscles. Next is the respiratory system. You speed up inhalation and exhalation to boost the runner's pace. You take in oxygen and breathe out carbon dioxide. When you sprint, you need way more oxygen and produce extra CO2. Thus, you rapidly and deeply increase your breaths. All this action takes place in tiny air sacs called alveoli in the lungs where gases swap places. VASCULAR SYSTEM In the vascular-system mini game, you guide a red blood cell. Your mission? Grab oxygen and glucose from the bloodstream and drop them off at those hardworking muscles. When the muscles get these essentials, they create ATP. That's what gives them the energy to help you move. The amazing thing is, while you're at it, the circulatory system is also whisking away CO2 and other trash that builds up in the muscles. ENDOCRINE SYSTEM Next up is the endocrine-system mini-game. This time, you're riding in a blood vessel on a quest to gather adrenaline hormones floating around in the plasma. Once pumped up with adrenaline, a person can sprint because their body ramps up its ability to react super fast. IMMUNE SYSTEM Then there's the immune-system mini-game. In this one, the runner gets a cut. Bacteria sneak in, ready to wreak havoc. As a white blood cell warrior, your goal is to stop those invaders from spreading. White blood cells are superheroes since they spot dangerous germs and take them out. Plus, the immune system keeps an eye on any hurt tissues and steps in so that everything inside your body stays balanced and running smoothly. Each system in the body does its own thing, but they all work together too. The nervous system lets your legs know when to run, the respiratory system brings in fresh oxygen and kicks out CO2. The vascular system then ships oxygen and glucose to the muscles for energy. When you're exerting yourself, the endocrine system gives out adrenaline to give that extra boost. Also, the immune system fights off any germs trying to cause trouble. Doing all these things lets the body keep going during exercise while staying balanced and safe. It's this teamwork that helps maintain homeostasis.
