Explanation:
Your lungs can store several hours worth of oxygen. The right lung is smaller than the left lung. The walls of the alveoli and capillaries are permeable.
Your body is not able to store oxygen. The extra supply of oxygen only works while you are breathing it in. When you take off the nasal cannula or mask, your oxygen levels may drop in a few minutes.
The cells in our bodies need oxygen to stay alive. Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
