1. eupnea
normal breathing, quiet breathing
2. coastal breathing
shallow chest breathing consisting of and upward and outward movement of the chest due to contraction of the external intercostal muscles
3. diaphragmatic breathing
deep abdominal breathing consists of outward movement of the abdomen due to the contraction and descent of the diaphragm
4. tidal volume
the volume of one breath is called this
5. minute ventilation
the total volume of air inhaled and exhaled each minute.  It is respiratory rate multiplied by tidal volume
6. spirometer
the apparatus commonly used to measure the volume of air exchanged during breathing and respiratory rate.
collectively, the conducting airways with air that does not undergo respiration exchange are known as this
8. Alveolar ventilation rate
is the volume of air per minute that actually reaches the respiratory zone
9. inspiratory reserve volume
by taking a very deep breath you can inhale more than 500ml.  This additional inhaled air is called this. 3100ml in male and 1900ml in female
10. expiratory reserve volume
normal inhalation plus forceful exhalation. 1200ml in males and 700ml in females
11. residual volume
even after exhalation, considerable air remains in the lungs because the alveoli stay slightly inflated, and some air remains in the non collapsible airways.  This can not be measured by a spirometer. 1200 in males and 1100ml in females
12. lung capacities
are combinations of specific lung volumes
13. inspiratory capacity
is the sum of tidal volume and inspiratory reserve volume
14. functional residual capacity
is the sum of residual volume and expiratory reserve
15. vital capacity
• is the sum of inspiratory reserve volume and tidal volume and expiratory reserve volume
• 4800ml in males and 3100ml in females
16. total lung capacity
is the sum of vital capacity and residual volume
17. Dalton's law
is important in understanding how gases move down their pressure differences by diffusion
18. partial pressure (Px)
the pressure of a specific gas in a mixture.  The subscript is the chemical formula of the gas.  The total pressure of the mixture is calculated simply by adding all of these pressure
19. Henry's law
the quantity of gas that will dissolve in a liquid is proportional to the partial pressure of the gas and its solubility.  It helps explain how the solubility of a gas relates to its diffusion. In the body the ability of a gas to stay in a solution is greater when its partial pressure is higher and when it has a high solubility in water.
20. external respiration or pulmonary gas exchange
is the diffusion of O2 from the air in the alveoli of the lungs to blood in pulmonary capillaries and the diffusion of C02 in the opposite direction
21. internal respiratory or systemic gas exchange
the exchange of O2 and CO2 between systemic capillaries and tissue cells.  As O2 leaves the blood stream oxygenated blood is converted to deoxygenated blood.  This occurs in tissues throughout the body.
