The respiratory system, as indicated in its name carries out the processes of respiration.
The processes of the transport of the respiratory gases are carried out by the circulatory system, a network of arteries, veins and capillaries, and NOT by the respiratory system (the lungs).

The right answer is b.transport of respiratory gases.

Breathing is the process by which oxygen from the air gets into your lungs and gets into your body. Our lungs take oxygen from the air and carry it into our bloodstream, which carries it into the tissues and organs that allow us to walk, talk and move. Our lungs also remove carbon dioxide from our blood, through the air we breathe.


The transport of respiratory gases is provided by the blood.

* Oxygen is transported for about 99% in bound form to hemoglobin present in red blood cells.

* Carbon dioxide is transported for about 20% in bound hemoglobin form, the remainder being either dissolved in the plasma or as bicarbonate ion due to its hydration.
