Respiratory system, diagram

Fig. 3.1 Schematic diagram of the human respiratory system. The gross anatomy of the lung, the covering membranes (pleura), airways and air sacs (alveoli) are shown. The average diameter of portions of the air flow system are indicated trachea, 20 mm bronchus, 8 mm terminal and respiratory bronchioles, 0.5 mnn alveolar duct, 0.2 mm alveolar sacs, 0.3 mm.

The rationale for basing air quality standards on smaller particles is evident from an examination of Fig. 2.12, a diagram of the human respiratory tract. Larger particles that are inhaled are removed in the head or upper respiratory tract. The respiratory system from the nose through the tracheobronchial region is covered with a layer of mucus that is continuously moved upward by the motion of small hairlike projections called cilia. Large particles deposit on the mucus, are moved up, and are ultimately swallowed.

From ferredoxin the electron pair returns to chlorophyll over a chain of redox catalysts (see left half of the diagram. Fig. 41). One of these redox catalysts— perhaps the first one—is the system plastoquinone/plastohydroquinone with a redox potential of 0.00 volt furthermore, cytochrome f is interposed here. The transport of electrons from plastoquinone to chlorophyll a E = H-0.45 volt) is coupled to a phosphorylation step just as in the respiratory chain, one inorganic phosphate is taken up and stored as ATP.
