The ______________________________ is composed of the chambers of the internal nose that function as a part of the upper respiratory system. 2. The ______________________________ is the most posterior part of the pharynx. It is shared by the respiratory system and the digestive system. The upper respiratory and upper digestive tracts diverge right after this structure. The front of this structure merges with the triangular entrance of the larynx. 3. The ______________________________ conveys air between the upper and lower respiratory structures. 4. The ______________________________ is a portion of the pharynx that begins at the rear of the nasal cavity and functions as an airway in the upper respiratory system. Its cavity always stays open, unlike the other parts of the pharynx. 5. The ______________________________ are two organs that are responsible for gas exchange. 6. The ______________________________ are the major airways of the lower respiratory system. 7. The ______________________________ are the main sites of gas exchange, where oxygen is brought into the bloodstream and carbon dioxide is removed. 8. The ______________________________ is a portion of the pharynx that is shared by the respiratory system and the digestive system. It functions as an airway in the upper respiratory system. 9. The ______________________________ are the major airways of the lower respiratory system. They link the trachea with the right and left lungs. They are wrapped in rings of hyaline cartilage, and their interiors are lined with mucous membrane. Fill in the blanks in the following statements:In ______________________________, air is inhaled through the nasal and oral cavities (the nose and mouth). Air moves through the pharynx, larynx, and trachea into the lungs. Then, it is exhaled, flowing back through the same pathway. Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called ______________________________. This respiratory process takes place through hundreds of millions of microscopic sacs called ______________________________. The bloodstream delivers oxygen to cells and removes waste carbon dioxide through _______________ Science Biology BIO MISC Share (0)
