The Respiratory System: Unit worksheet
Name: ___________
1.List 3 functions of the respiratory system___________________________________________________
2. List 3 functions of the paranasal sinuses ___________________________________________________
3. Small hairs in nasal cavity that move mucous and trapped debris___________________
4. Write the area of the pharynx that matches the following:
a) Nose: __________________ b) Mouth: _____________________c) Larynx___________________
5. Label the structure that matches the picture and
description. Then colorcode.
A. “Windpipe”; Carries air towards lungs
B. Grape-like clusters where gas exchange occurs
C. Large muscle that helps lift lungs during
D. The 2 primary respiratory organs______
E. Membrane that covers the lungs ______
F. Location of vocal cords______________
G. What the trachea branches into______
H. Common food and air passageway ___________
I. Closes larynx during swallowing _____
J. What bronchi branch into ____________
K. Warms and moistens air during breathing; traps
6. Put the following structures in order from smallest to largest: Bronchi, Trachea, Alveoli, Bronchioles
7. – Colorcode the oxygen rich areas
red and oxygen poor areas blue.
Then complete the paragraph below
using the choices provided
A. Aorta B. Diffusion C. Alveoli (used twice) D. Pulmonary arteries E. Oxygen F. Carbon dioxide
G. Vena Cava
H. Blood capillaries (used twice)
I. Pulmonary veins
All gas exchanges are made by a.___ as substances pass from high to low concentrations. After inhalation, oxygen
passes from an area of high concentration within the b.___ into an area of low concentration within the c.________.
Conversely, Carbon dioxide will pass from an area of high concentration within the d.____ into an area of low
concentration within the e.____ where it will then be exhaled. Blood is continuously circulated towards the lungs to be
oxygenated. Oxygen poor blood is carried from the right ventricle to the lungs via the f.______, while oxygen rich
blood is returned to the left atrium via the g. ____. From here, it will be pumped to the left ventricle and eventually
throughout the body via the h.____. As the vessels branch into capillaries, they will give off i. ___ to the cells and pick
up j. ____ causing the blood to become oxygen poor. The vessels will merge to form larger veins until they join to form
the k. __ that will return oxygen poor blood to the right atrium.
8. What 2 areas of the brain control the rate of breathing? ____________________________________
9. Breathing rate is mostly controlled by the blood concentration of which gas? _____________________
10. Why does breathing into a paper bag help during hyperventilation? ______________________________________
#s 11-16 - Write the term and the volume that corresponds to the description below.
Total Lung capacity
Residual volume
Inspiratory reserve volume
Tidal Volume
Vital Capacity
Expiratory Reserve
13. ________________________________________________________
14. ________________________________________________________
Air volume inhaled during normal breathing
Total amount of EXCHANGEABLE air
Total amount of air that lungs can hold
Amount of air that can be forcibly exhaled
after a normal breath
15. ________________________________________________________ Amount of air that can be forcibly inhaled
16. _________________________________________________________ Air remaining in lungs at all times
17. Explain how a lung sample can be used to determine if death occurred shortly before or after birth. ____
18. A device used to measure long capacity is called a/an: _______________________
19. Inspiration is a/an (active or passive) process. During this, the diaphragm and intercostals (contract or
relax), the ribs move (inward or outward), and the air pressure inside the lungs (increases or decreases).
Chronic bronchitis
Lung Cancer
Deviated septum
Heimlech maneuver
Cystic Fibrosis
Pulmonary edema
20._________________________________Describes normal breathing
21. _________________________________Cessation (stopping) of breathing (often at night)
22. _________________________________Labored breathing
23. _________________________________Describes an oxygen deficiency which can lead to cyanosis
24. ________________________________ Type of COPD where lung lose elasticity, alveoli fuse, and the chest enlarges
25. ____________________________Type of COPD where there is excessive mucous production and frequent coughing
26. __________________________________Condition where bronchial tubes spasm narrowing airways during attacks
27. __________________________________Uncontrolled cell division in lungs, often associated with smoking
28. __________________________________Bacterial infection of the lungs where lung tissue is destroyed
29. _________________________________Inflammation of the alveoli often caused by a viral or bacterial infection
30. __________________Genetic condition that affects ion channels in lungs causing the buildup of thick, sticky mucous
31. _________________________________Inflammation of the covering of the lungs causing painful breathing
32. __________________________Bacterial infection causing a distinct coughing sound; especially dangerous to infants
33. _________________________________Swelling of lung tissue due to osmotic imbalance
34. _____________________________Occurs when the tissue dividing the nostrils is uneven causing difficulty breathing
35. ________________________________Occurs as the vocal cords become swollen due to overuse or illness and are
unable to vibrate to produce sound
36. _________________________________Procedure that can be quickly done to dislodge food trapped in the airway
37. _________________________________Procedure where an opening is made in the trachea to re-establish airflow if
swelling or disease blocks the air passageway
38. ________________________________Medication injected to open airway in someone suffering anaphylaxis.
39. _______________________________An upper respiratory reflex used to rid the body of an irritant is called a/an:
40. _______________________________ A lower respiratory reflex used to rid the body of an irritant is called a/an:
41. _______________________________Reflex that occurs during changes in wakefulness; May increase oxygen levels
42. Explain why it is dangerous to talk or laugh while eating._______________________________________________
