Internal respiration

Breathing is the movement of air into and out of the lungs. Respiration is the exchange of oxygen and carbon dioxide. Oxygen is picked by and carried to the cardiovascular system and taken to the cells. The cells take up the oxygen and release the carbon dioxide back into the CVS and out to the lungs. The lungs take in oxygen and release carbon dioxide.
Guard cells allows the exchange of oxygen and carbon dioxide in and out of the leaf. This is known as leaf exchange. When guard cells are full of water they swell up and close meaning no oxygen can leave or carbon dioxide can enter, but when the water is taken away from the cell they open up to allow oxygen to exit and carbon dioxide to enter.
The hemoglobin in red blood cells carries oxygen from the lungs to the tissues in the rest of the body, where it releases the oxygen to the tissues and collects the resultant carbon dioxide bringing it back to the lungs to be exhaled.
Blood cells exchange carbon dioxide for oxygen. Neither is actually "air", as such.

No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Respiration is the process that carries oxygen to the cells and removes carbon dioxide from them. Blood carries the oxygen to the cells.
the surface of these cells are moist and the stomatas are open
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
The exchange of oxygen and carbon dioxide happens in between the alveoli and then through the walls of the capillaries and then into the blood. The oxygen is then picked up by hemoglobin in the red blood cells and sent to all body cells. While this is happening the carbon dioxide is transported back from the body cells and into the blood. It diffuses through the walls of the capillaries and into the walls of the alveoli. Carbon dioxide leaves your body whenever you breathe out.
