Figure 13-4 illustrates the gross anatomy of the lower respiratory system. Intact structures are shown on the left; respiratory passages are
shown on the right.
Select a different color for each of the structures listed below and use it to color in the coding circles and the corresponding
structures on the figure. Then, use the Key Terms to label the leader lines.

7. Many changes occur within the lungs as the diaphragm contract and then relax. These changes lead to the
flow of air into and out of the lungs. The activity of the diaphragm is given in the left column of the following
table. Several changes in condition are listed in the column heads to the right. Complete the table by checking
the appropriate column to correctly identify the change that would be occurring relative to the diaphragm’s
activity in each case.

8. Use the key terms to respond to the following descriptions. Insert the correct term or letter in the answer
blanks.
Key Terms
A. External Respiration
B. Expiration
C. Inspiration
D. Internal Respiration
E. Ventilation (Breathing)
1. ______ Period of breathing when air enters the lungs.
2. ______ Exchanges of gases between the systemic capillary blood and body cells.
3. ______ Alternate flushing of air into and out of lungs.
4. ______ Exchange of gases between alveolar air and pulmonary capillary blood.
9.
Four non-respiratory movements are described here. Identify each by inserting your answers in the spaces
provided.
Key Terms
A. Coughing
B. Laughing
C. Sneezing
D. Yawning
E. Hiccups
1. _____________________ Sudden inspiration, resulting from spasms of the diaphragm.
2. _____________________ A deep breath is taken, the glottis is closed, and air is forced out of
the lungs against the glottis; clears lower respiratory passageways.
3. _____________________ As just described, but clears the upper respiratory passageways.
4. _____________________ Increases ventilation of the lungs; may be initiated by a need to
increase oxygen levels in the blood.
