5 Written Questions

1. Larger and shorter (displaced by liver) and has three lobes.
2. Windpipe. 4.5" long. Walls are alternate bands of membrane and c-shaped rings of hyaline cartilage to keep it open. Lined with ciliated mucous membrane. Coughing and expectoration gets rid of dust-laden mucous.
3. Cavities in the skull, ducts connect them to the nasal cavity, lined with mucous membrane to warm and moisten the air. Give resonance to voice.
4. Divides nasal cavities into right and left sides.
5. Respiration (external, internal, and cellular). Production of sound (vocal cords). Pulmonary venilation. Inspiration (intercostal muscles lift ribs outward, sternum rises and the diaphragm contracts and moves downward- this increases the volume of the lungs and the air rushes in).

2. cilia
3. bronchioles
4. bronchial tubes
5. coughing

1. a Cartilaginous plates (instead of c-shaped rings of trachea).
2. b Smaller (displaced by heart) and has two lobes.
3. c Thinner walls of smooth muscle, lined with ciliated epithelium. Subdivision of bronci. At the end, alveolar duct and cluster of alveoli.
4. d Nose hairs, trap larger dirt particles.
5. e Deep breath followed by forceful expulsion of air to clean lower respiratory tract.

   1. types of sinuses
   2. turbinates

5 True/False Questions

1. chemical factors of breathing control → Respiratory center located in medulla oblongata (in the brain). Increase in CO2 and decrease in O2 in the blood will trigger respiratory center.

   True        False

2. pulmonary venilation → Throat. Common passageway for air and food. 5" long.

   True        False

3. alveoli → Composed of single layer of epithelial tissue. Inner surfaces covered with surfactant to keep from collapsing. Each surrounded by capillaries. Oxygen and carbon dioxide exchange takes place between these and capillaries.

   True        False

4. respiratory movement → 1 inspiration and 1 expiration= 1 respiration. Normal adult= 14-20 respirations per minute. Increases with exercise, body temperature, and certain diseases. Age (newborn= 40-60 per minute). Sleep= respirations go down. Emotion can bring respirations up or down.

   True        False

5. neural factors of breathing control → Respiratory center located in medulla oblongata (in the brain). Increase in CO2 and decrease in O2 in the blood will trigger respiratory center.

   True        False
