During inhalation or exhalation air is pulled towards or away from the lungs, by several cavities, tubes, and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the nose to the lungs.
Inside the air sacs, carbon dioxide moves from the blood into the air. At the same time, oxygen moves from the air into the blood in the capillaries. The oxygen-rich blood then travels to the heart through the pulmonary vein and its branches.The heart pumps the oxygen-rich blood out to the body.hey also carry carbon dioxide, a waste gas, out of your lungs. The airways include your: 1  Nose and linked air passages (called nasal cavities). 2  Mouth. 3  Larynx (LAR-ingks), or voice box. 4  Trachea (TRA-ke-ah), or windpipe. 5  Tubes called bronchial tubes or bronchi, and their branches.
