1) Unscramble the parts of the Respiratory System.
a) otlmirs -> nostrils
b) nyxrahp -> pharynx
c) alrxny -> larynx
d) gunl -> lung
e) bohcsunr -> bronchus
f) aipgamrhd -> diaphragm
g) rbhcio -> ribcage
h) nocelihorb -> bronchiole
i) aievoll -> alveoli
j) otuhm -> mouth
k) rthceaa -> trachea
2) Label the parts on this diagram of the Respiratory System.
(From top to bottom, left to right based on typical diagram layout)
- Pharynx (behind nasal cavity)
- Larynx (voice box)
- Trachea (windpipe)
- Right lung
- Left lung
- Diaphragm (muscle below lungs)
3) Find the parts of the Respiratory System
- BRONCHI
- PHARYNX
- LARYNX
- LUNGS
- TRACHEA
- DIAPHRAGM
- ALVEOLI
- NOSE
- MOUTH
- RIBCAGE
4) Select one or two parts and describe what they are used for in the Respiratory System.
The diaphragm is a large, dome-shaped muscle located at the base of the lungs. It contracts and flattens during inhalation, creating a vacuum that pulls air into the lungs. During exhalation, it relaxes and returns to its dome shape, pushing air out of the lungs.
The alveoli are tiny air sacs at the end of the bronchioles in the lungs. They are the site of gas exchange, where oxygen from the inhaled air diffuses into the bloodstream and carbon dioxide from the blood diffuses into the alveoli to be exhaled.
Parent Tip: Review the logic above to help your child master the concept of labeling the respiratory system worksheet.
