HOMEOSTASIS
big word.
that keeps you alive.
all of your cells need oxygen, a consistent temperature, a way to remove waste, a way to get energy.... your body has many ways of keeping it's internal environment constant.
Our CO2 Lab was one example of a homeostasis system. When you exercised, your cells needed more energy. That burning of energy requires oxygen, so, your heart rate increased to keep up with the demand. Your body uses glucose + oxygen to get energy and carbon dioxide through respiration.
