I have no idea what the oxygen levels were during the tertiary period!
aerobic respiration
Exercise regularly. Exercise increases blood circulation and oxygen levels. Walking, swimming and jogging are just a few exercises to help increase oxygen saturation. Lose weight and stop/quit smoking. In a medical situation, you can improve oxygen saturation by providing breathing oxygen.
low oxygen levels
Increased blood-flow and oxygen levels cause the fingernails to grow faster!
So the movement of oxygen in the body is different to the movement of carbon dioxide as while oxygen enters the red blood cells during this movement the carbon dioxide stays out. It stays in the plasma. Also for the movement of carbon dioxide to happen oxygen is needed. Its a product of aerobic respiration. The movement of oxygen in the body is similar to the movement of carbon dioxide as both processes require respiration and pass through the walls of the capillaries.
it increases.
