Food and nutrients in blood give energy to the muscles Nutrients from food are provided for bones (calcium for strong bones) 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 Blood, oxygen, and food are pumped to the muscles The liver removes waste products from the blood Oxygenated blood is pumped through the heart and then circulated through cells. Red blood cells move oxygen and carbon dioxide through the blood. Alveoli exchange gas with capillaries. Diaphragm, an involuntary muscle, forces breath in and out
