The process of respiration
Plants produce oxygen through photosynthesis and release it into the atmosphere where we can breathe it.
If this process is inadequate, oxygen levels in the blood decrease, and the patient may need supplemental oxygen.
carbon, hydrogen, oxygen....
transportation of oxygen in the blood stream
The body needs oxygen to survive, and blood carries oxygen to cells in the body.
The air carries oxygen to your body when it is inhaled into your lungs.The blood carries oxygen through you body to the vcells that use it as part of their metabolism.
Every cell in your body needs oxygen.
the human body needs oxygen and other nutrients to survive
Oxygen is needed by your body cells. You have got almost 20 % oxygen in the air. Rest is almost nitrogen and traces of other gases including carbon bi oxide. Oxygen is necessary for the biological oxidation process in the body. Every living cell of the body needs the same.
