  • Oxygen entering the body
  • Oxygen’s path to the air sacks
  • Traveling through the red blood cells
  • with four receptors, each blood cell is able to hold four oxygen molecules
  • The oxygen cell can enter the human body through two different forms, the mouth, or the nose.
  • When you inhale, oxygen travels first through your pharynx ( the back of your throat), then you larynx ( voice box), and finally into your trachea (windpipe). These tubes along with our nose are lined with cilia which filter bacteria and pollutants out of the air, and helps air flow, Your trachea is divided into the two bronchial air passages. Both tubes lead to the right and left side of the lungs respectively. At the end of each tube, is what we call alveoli.
  • Inside the air sacs, or the alveoli,oxygen moves across paper thin walls to tiny blood vessels called capillaries, then diffuses into your blood when you inhale.
