Respiratory System

4. Rapid or deep breathing that can cause a decrease in CO2 levels
7. fibrosis of lung tissue can lead to this type of pulmonary disease
8. Oxygen reversibly binds this molecule
9. Carbon dioxide is primarily transported in the blood as this.
11. A common test used to measure lung volumes and capacities
12. The double layered membrane that surrounds each lung
14. A condition characterised by a deficiency in the amount of oxygen reaching the tissues
16. This volume is the amount of air that moves in and out of the lungs with each respiratory cycle
18. Peripheral chemoreceptors are located in the aortic and _______ bodies
20. The air sacs at the ends of the respiratory tree
22. The nerve that controls the diaphragm
23. This type of pulmonary disease is caused by increased resistance to air flow
24. The total volume of air exchanged in the lungs per minute
25. the substance produced by the type II alveolar epithelial cells
26. The principle that describes how gases diffuse across a membrane
27. These types of receptors are located in the lungs and chest wall

1. The amount of air that can be forcibly expired from the lungs after a maximal inspiration
2. The widening of the bronchi and bronchioles, often caused by sympathetic nervous system stimulation
3. Acidosis will shift the Hb-O2 dissociation curve in this direction
5. A condition where the blood becomes too acidic, often due to high CO2 levels.
6. Stimulation of the smooth muscle in the bronchioles by the parasympathetic nervous system will cause this
10. A principle stating that pressure and volume are inversely proportional at constant temperature.
13. The site of gas exchange
15. Surface tension and density of elastin fibres can affect this property of the lung tissue
17. The direction the diaphragm moves when contracting
19. A substance that helps keep the pH stable
21. Pressure and volume have this type of relationship
