Respiratory System

Human Anatomy & Physiology

1. The movement of air within the repiratory system is correctly referred to as-Ventilation
2. Which reflex involves a spasmodic contraction of the diaphragm-Hiccup
3. The amount of air that can not be expelled is the-Residual volume
4. The internal nares will open into the-Nasal cavity
5. Tidal volume is air-Exchanged during normal breathing
6. Possible causes of hypoxia include-Too little oxygen in the atmosphere
7. The lung volume that represent the the total volume of exchangeable air is the-Vital capacity
8. Respiratory control centers are located in the -Medulla and pons
9. Surfactants helps to prevent the alveoli from collapsing by-Interfering with the cohesiveness of water molecule,thereby reducing the surface tension of alveolar fluid
10. The pleura that surrounds the lungs consists of two layers,the-Visceral and parietal pleurae
