Oxygen is transported first by air down the trachea and then transform to the hemoglobin of the blood to the cells. This is the pathway of oxygen in the human system.
Oxidation means addition of oxygen. When oxygen is added to a compound, it is said to be oxidised.
Quantitative
It is said to be anaerobic, which means "without oxygen". The opposite of "anaerobic" is "aerobic" which means requiring oxygen.

The leaves (needles in some cases) of trees inspire carbon dioxide (CO2) and expire oxygen (O2) when they are using sunlight to make food.

Anerobic respiration
You breathe in and the oxygen goes into your lungs. Your blood picks up the oxygen and carries it to your muscles, and then goes into the cells in said muscles.
Yes it does. But I don't know how. I just know it involves science. My teacher said so, but didn't tell me how it involves science.
Oxygen Debt
Yes, a tank of oxygen can be half full. The oxygen would be stuck in said tank meaning no more oxygen can get in unless refueld.
