Circulatory system.There is a duty to bring the oxygen from the lungs to cells to induce metabolic energy. Carbon dioxide and water. Carbon dioxide is taken out of the body by the lungs and also sent out come the out breath. 1. drain the air is a passage of air from the outside of the body, which has a high O2 enters the lung and air from the lungs, which has high CO2 out of the. 2. the lungs is responsible for providing a lot of space for the exchange of gases between the air in the lung parenchyma with new blood, which is the last part of the lung will have a small bag inside the capillaries, which provided for the exchange of O2 from CO2 into the blood, breath O2 will waste diffuses into capillaries, while CO2 will be reversed as the out breath through lungs, bronchial tubes nasal sinuses. The exchange of gas will continue to be so. A subsidiary of O2 gas pressure in the pulmonary parenchyma must be higher than the pressure of O2 in the blood-gas sub and sub CO2 of gas pressure in the pulmonary parenchyma must be lower than the pressure of CO2 gas in the blood is digested all the time, so new outside air must be brought into the lungs, and the polluted air from the lungs must be removed periodically to the outside all the time. Also, with the functionality of the pectoral muscle, and the commencement of the. To make the breast volume and expanded into a consistent rhythm, resulting in the lungs, which stuck to the wall, thoracic volume has changed along with it.
