Air has a constant concentration of 21 percent andwater has a constant concentration of 6 percent.d. For terrestrial animals, air is easier to move overrespiratory surfaces because it is less dense than water.
*Respiratory SystemThe respiratory system functions in the exchange of gases between the external and internalenvironments. Major parts of the system include the nasal cavity, larynx, trachea, bronchi, and pulmonaryalveoli. Some regions of the respiratory system are specialized for the conduction of gases and other areasfunction primarily in the exchange of gases. Filtration mechanisms exist in both regions. The function ofeach part of the respiratory system is reflected in the structure of its wall: the type of epithelium and itsapical modifications, intraepithelial and subepithelial glands, cartilaginous rings and plates, smoothmuscle and elastic tissue, and the relationship of capillary endothelium to alveolar epithelium.Study the Respiratory system in Slide Box and Respiratory system under EM.
