Across
- 5. membrane protects the lungs, provides a vacuum so that the lungs do not collapse
- 6. trachea divides into this,conducts air into the lungs, lined with ciliated epithilium
- 7. muscles between the ribs and pleural membrane, allows the person to breath
- 8. important muscle in respiration,vital component in the breathing process
- 10. made of fibrous and elastic tissue,embedded with rings of cartilage, warms the air
Down
- 1. cavity divided by a septum, contains ciliated epithelium, mucus traps particles and dust
- 2. passageway for air and food, supports speech, hearing and taste, humidifies air
- 3. primary organ in the respiratory system
- 4. gas exchange in the lungs takes place here,look like air sacs
- 6. cartilage starts to disappear here,controls rate of air with muscle contractions
- 9. reflex action closes trachea when swallowing,sound is produced here
