Why we need plants.
The Cycle the Oxygen Travels.
The air goes into the mouth and nose while being inhaled.
After the air is inhaled it enters the esophagus and then goes in to the lungs.
Middle and Last
The air goes into the heart and goes through out the body to reach air to all parts. Last, after the air goes through the whole body it then exits the mouth and nose.
