Red blood cells move oxygen and carbon dioxide through the blood. Alveoli exchange gas with capillaries. 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, oxygen, and food are pumped to the muscles The liver removes waste products from the blood Blood brings important nutrients from food (like calcium) to the bones Muscles of the digestive system need oxygen to function Nutrients from food are provided for bones (calcium for strong bones) muscles of the respiratory system need energy from digested food in order to function When there is a tear or injury in muscle nerves send messages to the brain Diaphragm, an involuntary muscle, forces breath in and out
