Ch.17B Flashcards
- What measurement device uses a bell, water and CO2 absorbent for measurements of breathing?
Older Spirometer
2.What diseases may spirometers be used to check for?
Emphysema, chronic bronchitis
3.The volume of air that moves in a single inspiration or expiration is;
Tidal Volume
4.The additional amount of air you can inhale beyond normal inhalation is;
Inspiratory reserve
5.The additional amount of air you can exhale beyond normal exhalation is;
Expiratory Reserve
6.The amount of air remaining in the lungs after maximal exhalation is;
Residue
7.Residual volume can be directly measured using a spriometer T/F
F
8.Tidal volume can be directly measured using a spirometer; T/F
T
9.The total lung volume minus the residual volume is;
Vital capacity
10.The maximal inhalation volume minus the maximal exhalation volume is;
Total lung volume minus the residue
11.During periods of high demand or low ventilation, blood leaving the alveoli may be inadequately oxygenated T/F
T
12.It is possible to drive oxygen levels above normal with hyperventilation T/F
T
13.The cells of the alveoli must be ____ in order to facilitate diffusion of gasses
Thin
14.The liquid that is secreted by the alveoli in order to prevent the surfaces from sticking together is called;
Surfactant
15.The liquids of the alveoli and pleural membranes have a similar function T/F
F
16.What tissues are contained within the alveoli that help with exhalation?
Elastic fibers
17.Most of the alveolar surface is covered with capillaries T/F
T
18.The amount of blood flowing around an alveolus is called;
Perfusion
19.What normally occurs when the oxygen levels in an alveolus are reduced (due to inadequate ventilation)?
Ventilation perfusion
20.When the amount of blood moving around the alveolus does not match the oxygen levels in that alveolus, this is called;
Mismatch ventilation perfusion
21.Perfusion-ventilation matching is normally under control of the medulla T/F
F
22.What is/are the functions of the goblet cells of the respiratory tract?
produce mucus to trap inhaled particles
23.How does the mucus in the respiratory tract not stick to the epithelial cilia?
Saline
24.What two structures work together to help breathing occur?
Ribs with intercostal, and diaphragm
25.Oxygen and carbon dioxide move into or out of the blood independent on the concentration of the other gas T/F
T
26.What problem/factor can limit ventilation efficiency?
Airway resistance can limit ventilation efficiency
27.Typically ventilation matches perfusion in the lungs T/F
T
