pleural layer lining the walls of the thorax | parietal pleura |
site from which oxygen enters the pulmonary blood | alveolus |
connects the middle ear to the nasopharynx | pharyngotympanic tube |
opening between the vocal folds | glottis |
increase air turbulence in the nasal cavity | conchae |
separates the oral cavity from the nasal | palate |
What portions of the respiratory system are referred to as anatomical dead space | Conducting zone |
Why are conducting zones considered anatomical dead space | because there is no gas exchange |
External respiration | Exchange of gas across a respiratory membrane |
Internal respiration | exchange of gases between systemic blood and tissue cells |
Cellular respiration | Cells use oxygen and release carbon dioxide |
