The respiratory system.
the lungs bring it in from the air to the body but the circulatory system takes it around the body
the tube
It is called breathing. Breathing is the movement of the chest that brings air into the lungs and removes waste gases. The air entering the lungs contain oxygen. It passes from the lungs into the circulatory system because there is less oxygen in blood when it enters the lungs than in the cells of the lungs.

When your lungs move to bring in air and remove gases you are breathing.
Your respiratory system is the system that brings oxygen onto your body and is mainly associated with the lungs and the windpipe bringing the air down from your mouth. Teh ribs are the bones of your chest that curve round your lungs. They form a cage around the lungs which stops the lungs being crushed. If your lung is pressed flat it cannot take in air. It needs to be inflated like a balloon. Without your ribs every time you came into contact with something it would push the air out of your lungs and wind you.
The respiratory system. The alveoli are air sacs in the lungs.
the pulmonary.
Benefits of the respiratory system are: It helps the body to regulate temperature by expelling heat. The respiratory system brings air into the lungs and ultimately to each cell in the body. The respiratory system also removes carbon dioxide from the body.
Diaphragm, the spelling of that was kind of a guess, but you get what I mean. :)
Breathing or Respiration
The respiratory system draws oxygen into the lungs. The circulatory system moves blood into the lungs to pick up the oxygen and then brings the oxygen to cells in the rest of the body.
The mouth and nose serve to bring air in and out of the body. The trachea brings air from the nose and mouth to the lungs and vice versa. The lungs hold the bronchi which are groups of avioli .The alvioli serve as docking stations where blood cells can exchange co2 for oxygen they take to the rest of the body.
