Windpipe, is about 11 cm (4.5) that extends from the larynx in the name of the bronchi and the chest cavity |
|
|
Surfactant |
-The surface of the respiratory membrane inside each alveolus is covered by this substance -Helps reduce surface tension in the alveoli and keeps them from collapsing as air moves in and out during respiration |
|
|
Pleura |
Covers the outer surface of a lines the outer surface of the rib cage |

21.1mL combines with hemoglobin in 100mL of blood to form this to carry the tissue and used by the body cells |
|
|
Heme |
Hemoglobin molecules are large portions that contain for iron-containing components Each of which is capable of combining with an oxygen molecule |

|
|
Chemoreceptors |
Located in the carotid and aortic bodies specialed receptors that are sensitive to increase in blood carbon dioxide level and decrease in blood oxygen level |
