12is the process by which oxygen and carbon dioxide are exchanged from areas of high concentration to areas of low concentration at the air blood interface
- Apulmonary diffusion
- Bpulmonary perfusion
13this process is when actual blood flow through the pulmonary vasculature the blood is pumped into the lungs by the right ventricle through the pulmonary artery

14perfusion is influenced by pulmonary artery pressure, gravity and
- Aalveolar pressure

16can cause increased airway resistance
- Acontraction of bronchial smooth muscle such as asthma
- Bthickening of bronchial mucosa such as in chronic bronchitis
- Cobstruction of the airway by mucus tumor or foreign body
- Dloss of lung elasticity such as emphysema
- Eall of the above
17gas exchange between that atmospheric air and the blood in between the blood and the cells of the body is called
- Arespiration
- Bventilation
18this requires movement of the walls of the thoracic cage and diaphragm during inspiration and expiration
- Aventilation
- Brespiration
19gas exchange with oxygen is by
- Adiffusion
- Bbreathing
- Cnot breathing
20this type of ventilation and perfusion imbalance happens when ventilation exceeds perfusion such as a pulmonary embolism causing inadequate perfusion
- Adead space
- Bshunt perfusion
- Csilent unit
21this type of imbalance happens with an inadequate ventilation and not enough oxygen is coming in such as a lung collapse
- Ashunt perfusion
- Bdead space
- Csilent unit
22this in balance is when inadequate ventilation and inadequate perfusion is involved such as a pneumothorax or ARDS
- Asilent unit
- Bshunt perfusion
- Cdead space
23the amount of blood passing by the alveoli is equal to the amount of gas with a normal ratio of 1 to 1 is called
- AV/Q ratio

- CR/v ratio
24these two structures control respiratory and are located in the brain stem
- Amedulla oblongata and pons
