HAVE TO LABEL ON QUIZ

Question 3

• Normal pathway fro air to enter the respiatory system
• internal part of the nose is called the nasal cavity
• divided into 3 passageways call nasal concha
• as air enters, it is warmed, moistened, and filtered

Answer 3

nose

Question 4

• also known as the throat
• common passage for repiratory and digestive systems
• nasopharynx is part of the pharynx behind nasal cavity
• oropharynx is part of the parynx behind mouth

Answer 4

pharynx

Question 5

• serves as air passage and for production of sound
• small opening on top of larynx is called the glottis
• contains 2 sets of heavy folds called vocal cords
• vibrate when air is exhaled to create the voive

Answer 5

larynx

Question 6

• also known as the windpipe
• carries air from the larynx to the brronchialtree
• held open by C-shaped rings made of cartilge rings
• lined with mucus and cillated cells that filter air

Answer 6

trachea

Question 7

• pair of cone-shaped organs in the thoroeic cavity
• primary organs of breathing and gas exchange
• contain numerous air passages, blood vessels, and millions of tiny air sacs called alveoli

Answer 7

lungs

Question 8

• network of tubes that conduct air though the lungs
• at the top, the trachea spilts into 2 large bronchi
• tubes narrow until they are called bronchioles
• at bottom, tubes divide into the smallest terminal bronchiles

Answer 8

bronchial tree

Question 9

• lungs contain over 500 million air sacs
• location where lungs and blood exchange O2 and CO2
• lining of each alveolus is only 1-cell thick
• allows for gas exchange by process called diffusion

Answer 9

alveoli
