well, the process where blood exchanges oxygen for carbon dioxide is called gas exchange system also called delivery system. That's what I know, and i hope it's true.

Oxygen exchanges occur in the lungs where the circulatory system takes in oxygen and releases carbon dioxide into the lungs. Oxygen exchanges also occur in the capillaries where the circulatory system delivers oxygen to the cells and picks up carbon dioxide from the cells.
The respiratory
oxygen-carbon dioxide cycle
We inhale air. Our lungs filter out the needed oxygen which is sent to the tissues of our body. In the process, the lungs get rid of waste by exhaling carbon dioxide.
the respiratory system
gases - specifically carbon dioxide and oxygen
organ system
Oxygen and carbon dioxide
Oxygen passes into the blood and carbon dioxide leaves it through the walls of the capillaries which surround the alveoli in the lungs. It's not really correct to use terms like 'pump' and 'collect', as this is a simple process of diffusion.
