- In insects, the respiratory system involves structures called tracheal tubes. How do the tracheal tubes provide oxygen to the insects body?The function of pharyngeal gills includes: ( can be more than one anwser) a. gas exchange b. generating a feeding current c. eliminating excess water during feeding d. producing a mucous netAdult frogs and toads obtain oxygen througha. gills only.b. gills and lungs.c. lungs and skin.d. lungs only.
- Sponges and cnidarians have no lungs or gills. How do they exchange gases with the environment? Are humans better off having lungs? If so, how?All vertebrates breathe with either gills or lungs. Which is a property of gills only and not lungs?Match the respiratory organs of FROGS to their functions. 1. Nasal Cavity A. The short tubes of a frog’s breathing system that leads from the larynx to the lungs; passageway of air into the lungs. 2. Glottis B. Amplify the advertisement call of the male and attract females. 3. Pharynx C. Where gases are exchanged between the air and the bloodstream. 4. Trachea D. Passageway of air from the external environment. 5. Larynx E. Allows air to enter glottis then into the larynx. 6. Vocal Sacs F. Controls airflow in and out of the respiratory passages. 7. Bronchi G. Connects the pharynx with lungs. 8. Lungs H. Contains vocal cords; used to conduct air to the lungs and as a voice box so the frog can communicate. 9. Alveolar Ducts I. Exchange point where CO2 leaves and O2 enters the blood. 10. Alveoli J. Tiny tubes that connect the respiratory bronchioles to alveolar sacs. K. Divides the left and right lung.
- Do beings of the classReptilia perform gas exchangein the same way amphibiansdo?Describe structural and functional differences between gills and lungs (ie. know the anatomy of lungs and gills). Why are birds’ lungs more efficient at removing O2 from the air compared with mammalian lungs?How does the respiratory system of a frog change when itundergoes metamorphosis?
