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.
