The circulatory system.Is the oxygen from the lung to cause cells to metabolic energy, carbon dioxide and water and carbon dioxide are removed outside the body by are then transported to the lungs and export the breath, the heart out.1 pipe air passages, a main was the passage of air from the outside of the body, which is O2 high into the lungs and the air from the lungs, which have. High CO2 exit.2. Lung, providing many areas for gas exchange between the air bag new wind lung and blood, which the final part of the lung is a small bag The capillaries for exchange O2 of breath with CO2 from blood O2 will spread into the capillaries. While CO2. To ย้อนทาง faint exhale through the stage lung, trachea, nasal cavity through the nostril. Gas exchange will continue, the partial pressure of the gas. O2 in pulmonary alveoli must be higher than the partial pressure of the gas O2 in blood and partial pressure of the gas in the alveoli CO2 ปอดจะ under partial pressure of the gas. CO2 blood all the time. So the fresh air outside must be brought to the lungs. The polluted air from the lungs must be taken out to the outside. Periodically all the time. As with the function of muscle chest and diaphragm. In this volume chest expand and shut out the rhythm. As a result, the lungs, which are attached to the chest wall to change the volume too.
