 | | Respiratory system organs are divided functionally into conducting zone structures (nose to bronchioles), which filter, warm, and moisten incoming air; and respiratory zone structures (respiratory bronchioles to alveoli), where gas exchanges occur. | | | Nonrespiratory air movements are voluntary or reflex actions that clear the respiratory passageways or express emotions. | | | 2. The pontine respiratory group (and perhaps other respiratory centers in the pons) influence the activity of the medullary inspiratory center. |

| | (Respiratory) Lungs |
| | The conducting zone structures contain all the passages to and from the respiratory zone. | | | The respiratory zone structures eventually divide to become the alveoli. | | | The lungs are the primary organs of the respiratory system. |

| | Respiration |
| | The conducting zone is the portion of the lungs that aids in the movement of air in and out of the surrounding environment, and sets the initial availability of air to move into the respiratory zone. | | | Ventilation moves air in and out of the respiratory zone through the conduit pathways of the conducting zone. | | | The overall process of pulmonary ventilation is to move air in and out of the lungs (breathing) through the contraction and relaxation of the diaphragm and intercostal muscles. |

| | Respiratory System |
| | Thus, respiratory therapists refer to the branching pattern inside the lungs as the generations of the bronchial tree. | | | The transitional and respiratory zones begin with the respiratory bronchioles which correspond to generations 17 through 19 in this system. | | | An extensive, respiratory pathway begins at the nose and ends in the lungs. |

| | THE LOBULAR-ALVEOLO-CAPILLARY CYCLES |
| | The physiological equilibrium of the pulmothorax dynamics in this zone and specifically at this moment depends upon the physiological equilibrium in the pulmonary arterial area in one direction, farther on in the right ventricle and even farther on, in the tissue area. | | | The displaced volume-mass of air from the ventilatory zone has now acquired new conditions: Its volume has been reduced and its pressure has increased in a converse relationship. | | | At this moment, which corresponds to vertical 3, a sudden decrease of the sub-atmospheric intra-pleural pressure begins, preceding the fall equally sudden of the respiratory impulses. |

| | INTRODUCTION TO THE KINETICS OF THE PLEURAL SPACE |
| | Among the effects determined by this primary force is the evocation of reflexes which also determine actions and reactions, from which new reflexes with their consequences are generated. | | | This space must offer the mechanical conditions for the elastic play of the pulmo-thorax structures, in order to make possible the mechanics of low intensity that characterise the pulmonary peripheral area, represented by the lobular and alveolo-capillary structures or respiratory zone, as referred to above. | | | This determines a strong primary pulmonary retraction, and evokes the reflex diaphragm contraction while accumulating potential energy. |
