Respiratory and circulatory

muscles of the respiratory system need energy from digested food in order to function

Muscles of the digestive system need oxygen to function

Brain regulates heart rate and blood pressure

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.

When there is a tear or injury in muscle nerves send messages to the brain

Diaphragm, an involuntary muscle, forces breath in and out

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

The liver removes waste products from the blood

Blood, oxygen, and food are pumped to the muscles

Nutrients from food are provided for bones (calcium for strong bones)

Blood brings important nutrients from food (like calcium) to the bones

digestive system sends messages to brain when your hungry or full
