digestive system sends messages to brain when your hungry or full
Spinal column protects the spinal cord. Skull protects the brain
The liver removes waste products from the blood
Brain regulates heart rate and blood pressure
muscles of the respiratory system need energy from digested food in order to function
Muscles of the digestive system need oxygen to function
Tells respiratory system to supply more oxygen when needed
Nutrients from food are provided for bones (calcium for strong bones)
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.
Blood brings important nutrients from food (like calcium) to the bones
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
When there is a tear or injury in muscle nerves send messages to the brain
Blood, oxygen, and food are pumped to the muscles
Controls the rate of breathing
Ribs protect lungs
Diaphragm, an involuntary muscle, forces breath in and out
Muscles work with bones to cause movement
