Red blood cells move oxygen and carbon dioxide through the blood. Alveoli exchange gas with capillaries. Brain regulates heart rate and blood pressure digestive system sends messages to brain when your hungry or full muscles of the respiratory system need energy from digested food in order to function Muscles in the jaw help the teeth grind the food, and the involuntary smooth muscles of the stomach breaks down the food. Food and nutrients in blood give energy to the muscles Blood brings important nutrients from food (like calcium) to the bones
