 * Oxygen and Food = Energy**

Glucose + O2 = Release Energy ad the waste is C02 + H20

- happens in all your trillion cells

Fermentation: Food ---> Little Energy (the waste is CO2 and lactic acid)

O2 = Two Oxygen Atoms


 * Internet Notes:**

Respiratory system is the system that helps you breath in and out so oygen gas can be pumped through your body and CO2 can be removed from the blood stream.

Nose is for Breathing Oxygen

Nose - Sinuses Nasal Passages (Filters: Hair, Mucus,) - Pharynx (Throat)

Two Passages: Trachia (Wind Pipe) and Esophagus (Food)

2 Lungs: Bronclus, Bronchiolos, Air Sacs (alveoli) - where gas exchange occurs from CO2 to a.s. to O2 to A.s.

Diaphragm = how we get oxygen into lungs, muscle,
