22. The Respiratory System

Which of the following would best predict how likely someone is to blow out all their birthday candles in a single breath?

The typical person has about 150 ml anatomical dead space. If the typical tidal volume is about 500 ml, how much air that starts completely outside the body actually makes it to the alveoli with each inspiration?

Under normal conditions which of the following volumes do you expect to be the smallest?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

The vital capacity is the total amount of exchangeable air.

Distinguish between inspiratory reserve volume (IRV) and inspiratory capacity (IC)?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

The inspiratory capacity is equal to the vital capacity plus the tidal volume.

The Functional Residual Capacity can be thought of as a combination of which other measures of lung volume?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

The tidal volume is the amount of air left in the lungs after maximal expiration.

Of the following four lung volumes, which do you think would be the hardest to measure without advanced instrumentation?

Mark the following statements as true or false. If a statement is false, correct it to make a true statement.

The functional residual capacity is the volume of air normally left in the lungs after a tidal expiration.

What are the differences between pulmonary volumes and respiratory capacities? How are pulmonary volumes and respiratory capacities determined?
