Oxygen
The journey starts...
- The oxygen enters the body through nose/mouth
- It moves through your trachea
- From your trachea the oxygen travels into and through your lungs until it arrives at the bronchi.
- The bronchi are where the oxygen is released into the blood vessels. The red blood cells in the plasma of the blood vessels transport the oxygen throughout the body.
Then, the cardiovascular system kicks in!
- The blood vessels circulate the oxygen so that it can supply the other cells of the body. Cells cannot function without oxygen. Since cells make up tissue, and tissue make up organs, and organs make up organ systems. The organ systems...
The systems:
-
...the skeletal system
Within the marrow of the bones new blood cells are produced which are vital to the circulation of oxygen.
...the digestive system
The liver produces bile, in order to do this the cells require oxygen.
...the lymphatic system
If, while travelling some plasma leeks out of the blood vessels, the lymphatic system will regulate this error and scan the fluid for infections.
-
-
...the nervous system
The brain is an extremely important part of the nervous system and therefore requires a lot of oxygen to function and send signals.
-
...the muscular system
The heart is part of the cardiovascular system but also the muscular system. In the muscular system, it is part of a group of muscles called cardiac muscles.
- After the oxygen rich blood has flowed throughout the whole body, the blood returns back to the lungs where the used oxygen from the cells (or CO2) will be exchanged for new oxygen.
- The CO2 then exits through the lungs, trachea and the nose and/or mouth.
