An external oxygen delivery system would consist of an oxygen source (such as a pressurized gas chamber), a pressure relieving system and a delivery system such as a breathing tube.
pathway of oxygen
The respiratory system.
Respiratory System
The blood circulatory system.

6C02 + 6H2O +light energy -> 6O2 + C6H12O6(glucose)
The byproducts of photosynthesis are oxygen and glucose. These are made when the processes known as the Kalvin Cycle and the Krebs Cycle.
This occurs naturally without any effort.
the respiratory system brings oxygen into the body
Three byproducts of photosynthesis are glucose, oxygen and water.
oxygen is breathed into the lungs where 'gaseous exchange' takes place, this transfers the oxygen to the blood supply (circulatory system) which already contains various substances ie. food etc. Oxygen is taken via the blood capilary network to the muscle cells 'mitchocondria' where 'airobic resperation' takes place, this involves the food being broken down using the oxygen, releasing energy to the cells and producing carbon dioxide and water as byproducts.
The oxygen in the uvula first combines with the red blood cells and the co2 combines with the whit blood cells
Blood and oxygen are transported by the circulatory system.
