Hemoglobin
40
Hemoglobin binds ______ and ________ together in RBCs
- oxygen | - carbon dioxide
41
The gas exchange at cell level is called
Cellular respiration
42
Upper respiratory tract includes (4)
1. Nasal cavity 2. Nose 3. Paranasal sinuses 4. Pharynx
43
What does the larynx do
Filter air
44

45
In vocal cords, decreased tension = ______ pitch
Lower
46
In vocal cords, higher tension = ______ pitch
Higher
47

Epiglottic cartilage
48

Vocal cords from vibrating freely
49
Windpipe
Trachea
50
The trachea is lined with...?
Mucous membrane
51
Branched airways leading from trachea to microscopic air sacs in lungs
Bronchial tree
52
Lungs are generally...? (Characteristics)
Soft and spongey
53

3000 mL
57
Normal expiratory reserve volume (#)
1100 mL
58
Residual volume (#)
1200 mL
59
More O2 is released with CO2 levels _______
Increase
60
Most CO2 is transported as ...?
Bicarbonate ions
61
Infection in airsacs - inflammation filled with fluid. Other illnesses lead to it because of a weakened immune system and you are breathing in bacteria
Pnemonia
62
Chronic lung disease that inflames + narrows airway
Asthma
63
Inflammation + mucus in bronchial tubes - leads to air restriction
Acute / chronic bronchitis
64
Improper amount of air in alveoli; lost volume in all/part of your lung (collapsed lung)
Atelectasis
65
Cancer in lungs - abnormality in cells that cause malignant tumor
Lung cancer
66
Airsacs in lungs = damaged and lead to difficulty breathing
Emphysema
67
Genetic disease that causes lung infection and limits ability to breathe over time. Genetic gene cause buildup of mucus in lungs, pancreas and other organs. Mucus clogs airways and traps bacteria leading to infections
Cystic fibrosis
