What are the parts of a respiratory system top to bottom?

Answer 1

In order (the path of air) ; The nose. The Pharynxa.k.a the throat. the trachea. the bronchi. and the lungs. The respiratory system is rather simple: a breath starts out when a person clenches their diaphragm, creating a vacuum that the air is drawn into. The air enters in the trachea, or windpipe, going through one of the two bronchial tubes, which branch into smaller bronchioles. The bronchioles end in small sacs called alveoli, which have capillaries in them. The carbon dioxide in the blood in the capillaries is then exchanged for the oxygen in the air by diffusion. When that is done, the now oxygenated blood travels all over the body, supplying oxygen where it is needed. Then, the diaphragm relaxes, and the carbon dioxide rushes out of the alveoli, through the bronchioles and the the bronchial tubes, and out of the trachea, and out of the body through the nose or mouth. Then, it is done, and the diaphragm clenches...

Answer 2

1. external nares

2. internal nares

3. sinuses

4. pharynx

5. uvula

6. epiglottis

7. glottis

8. trachea

9. larynx (vocal cords)

10. bronchi

11. bronchioles

12. alveoli

13. (11 and 12 make up the lungs)

Answer 3

in this order...

• nose
• nasal cavity
• pharynx
• epiglottis
• larynx
• trachea
• bronchi

so basically it goes through the nose, nasal cavity, pharynx, epiglottis, larynx, trachea, then through the bronchi which are in the lungs.

Answer 4

alveolar ducts, alveolar sacs, terminal bronchioles, respiratory bronchioles, bronchi, bronchioles

Answer 5

External nares

Answer 6

lungs
