Across
- 4. The name of the system that supplies the body with oxygen and the removal of carbon dioxide.
- 5. ---'s law governs ventilation, the movement of air into and out of the lungs and examines changes in thoracic volume.
- 10. Also known as breathing in. External intercostal muscles contract causing the rib cage to elevate and the diaphragm contracts causing it to move downwards.
- 14. The --- consists of respiratory bronchioles, alveolar ducts, and alveoli. The site of gas exchange.
- 15. These prevent the trachea from collapsing.
- 16. --- respiration occurs between the lungs and blood. Partial Pressure O2 is higher in alveoli compared to in pulmonary capillaries.
Down
- 1. Also known as breathing out. Does not involve muscles contracting. External intercostal muscles relax causing the rib cage to return to its original position.
- 2. Oxygen and haemoglobin combination.
- 3. --- is the pressure exerted by a gas in a mixture and is directly proportional to its percentage.
- 6. Detects changes in chemical composition within the blood and relays information to respiratory centers to adjust breathing.
- 7. The --- conducts air to the respiratory zones. It filters, humidifies, and warms the air.
- 8. --- respiration occurs between the blood and tissues. Partial Pressure O2 in systemic capillaries is higher compared to in cells as oxygen diffuses from blood to tissues.
- 9. ---'s law looks at total pressure exerted by a mixture of gases.
- 11. ---'s law looks at gas mixtures when in contact with liquid and how each has dissolved in proportion to its partial pressure.
- 12. Pushes debris trapped by mucus upwards towards the pharynx.
- 13. The movement of oxygen and carbon dioxide by simple diffusion along a concentration gradient.
