Explanation / Answer

1 Large dome of skeletal muscles that when contracted expands the superior-inferior dimension of the thoracic cavity Boyle's law.

2. As diaphragm relaxes, thorax volume decreases, leading to exhalation

3. Respiratory centers are located in medulla, pons

4. Pressure exerted by each type of gas in a mixture is known as partial pressure.

5. Partial pressure of a gas increases with increase in the concentration of a gas.

6. Partial pressure of N2 in air is 593 mmHg

7. Henry's law states that solubility of a gas in liquid increases with increase in partial pressure of that gas.

8. Boyle's law states that pressure of a gas is inversely related to the volume of a gas at constant temperature.

9. Dalton's law states that partial pressure of individual gases in the air is related to total atmospheric pressure and concentration of gas in a mixture.
