Across
- 2. – Leaf-shaped cartilage that closes over the larynx during swallowing
- 6. – Scarring of lung tissue, leading to a restrictive lung disease
- 10. - This type of binding of O2 molecules is responsible for the sigmoid dissociation curve of hameoglobin
- 12. – Effect describing how increased CO2 or decreased pH reduces haemoglobin's oxygen affinity
- 14. -The key transmural pressure that allow lung expansion.
- 16. – A key protein in RBCs responsible for oxygen and CO2 transport
- 17. – Volume of air moved in and out of the lungs during normal respiration
- 18. – Area in the respiratory system where no gas exchange occurs
- 19. – Ring of cartilage in the larynx
- 20. – Also known as the voice box, protects the airway during swallowing
Down
- 1. – The ion involved in the shift that occurs when bicarbonate exits red blood cells
- 3. – The pressure within the pleural cavity, usually lower than atmospheric pressure
- 4. – The law describing the rate of diffusion of gases across a membrane
- 5. – The pleura covering the lungs
- 7. – Hair-like structures in the respiratory tract that help move mucus
- 8. – A form of COPD where alveolar walls are destroyed, causing airway obstruction
- 9. – The ability of the lung to stretch and expand
- 11. – Environmental factor that causes a rightward shift in the oxygen dissociation curve due to lower oxygen availability
- 13. – A condition in which there is low pO2 in arterial blood
- 15. Primary muscle of respiration, innervated by the phrenic nerve
