Respiratory System

5. Stimulation of the smooth muscle in the bronchioles by the parasympathetic nervous system will cause this
6. The total volume of air exchanged in the lungs per minute
8. These types of receptors are located in the lungs and chest wall
10. The air sacs at the ends of the respiratory tree
11. Acidosis will shift the Hb-O2 dissociation curve in this direction
13. Pressure and volume have this type of relationship
15. Peripheral chemoreceptors are located in the aortic and _______ bodies
20. Carbon dioxide is primarily transported in the blood as this.
24. The widening of the bronchi and bronchioles, often caused by sympathetic nervous system stimulation
26. The direction the diaphragm moves when contracting
27. The site of gas exchange

1. fibrosis of lung tissue can lead to this type of pulmonary disease
2. A common test used to measure lung volumes and capacities
3. Rapid or deep breathing that can cause a decrease in CO2 levels
4. This type of pulmonary disease is caused by increased resistance to air flow
7. The amount of air that can be forcibly expired from the lungs after a maximal inspiration
9. The nerve that controls the diaphragm
12. Oxygen reversibly binds this molecule
14. Surface tension and density of elastin fibres can affect this property of the lung tissue
16. The double layered membrane that surrounds each lung
17. A substance that helps keep the pH stable
18. the substance produced by the type II alveolar epithelial cells
19. A principle stating that pressure and volume are inversely proportional at constant temperature.
21. A condition characterised by a deficiency in the amount of oxygen reaching the tissues
22. This volume is the amount of air that moves in and out of the lungs with each respiratory cycle
23. The principle that describes how gases diffuse across a membrane
25. A condition where the blood becomes too acidic, often due to high CO2 levels.
