Ventilation rate = tidal volume × breathing rate (per minute). (11, 4) 4. the volume of air which moves into and out of the lungs with each resting breath. (5, 6) 5. the main airway, supported by incomplete rings of cartilage, which carries warm moist air down from the nasal cavity into the chest. (7) 6. the gaseous exchange organs of fish, comprised of gill plates, gill filaments and gill lamellae. (5) 7. blood that has passed through the gas exchange organs (e.g. lungs) and is high in oxygen. (10, 5) 8. the compound formed when haemoglobin accepts free hydrogen ions in its role as a buffer in the blood. (13, 4) Down 2. the ability to return to original shape and size following stretching. (7, 6) 3. the volume of air that is left in the lungs after forced exhalation. It cannot be measured directly (8, 6) 9. the bony flap covering the gills of bony fish. Part of the mechanism that maintains a constant flow of water over the gas exchange surfaces. (9) 10. the effect of carbon dioxide concentration on the uptake and release of oxygen by haemoglobin.
