Respiratory System Each day we breathe about 20,000 times. All of this breathing couldn't happen without help from the respiratory system, which includes the nose, throat, voice box, windpipe, and lungs. With each breath, you take in air through your nostrils and mouth, and your lungs fill up and empty out. As air is inhaled, the mucous membranes of the nose and mouth warm and humidify the air.

1 Tiny hairs called _____ protect the nasal passageways and other parts of the respiratory tract, filtering out dust and other particles that enter the nose with the breathed air.

1 Cilia Home

2 The two openings of the airway (the nasal cavity and the mouth) meet at the __________, or throat, at the back of the nose and mouth.

2 Pharynx

3 The __________, a small flap of tissue, covers the air-only passage when we swallow, keeping food and liquid from going into our lungs.

3 Epiglottis

4 The _______, or voice box, is the uppermost part of the air- only passage.

4 Larynx

5 At its bottom end, the trachea divides into left and right air tubes called _______, which connect to the lungs.

5 Bronchi

6 Within the lungs, the bronchi branch into smaller bronchi and even smaller tubes called ____________

6 Bronchioles

7 The lungs contain elastic tissues that allow them to inflate and deflate without losing shape and are encased by a thin lining called the ___________

7 Pleura

8 The ________, which separates the chest from the abdomen, plays a lead role in breathing.

8 Diaphragm
