What are the three functions of a ventilatory system?
Compare ambient, tracheal, and alveolar air.
Describe the two ways that oxygen is transported in the blood.
Describe the three ways that carbon dioxide is transported in the blood.
Explain the mechanics of ventilation.
Compare static and dynamic lung volumes.
What is the formula for Minute ventilation?
Define: dysnea, hyperventilation, and Valsalva maneuver.
Describe the relationship between tial volume, inspiratory reserve volume,
expiratory reserve volume, residual volume, and vital capacity.
10- Place the following terms in order of air flow movement during the inspiratory
cycle:
Bronchioles, trachea, alveoli, and bronchi
11- Give the surface area of the lungs.
12- What is the primary function of the alveoli?
13- What three muscles are involved in inspiration?
14- Discuss the contributions of breathing rate and tidal volume to the increased
ventilation during moderate and heavy exercise.
15- What is the average partial pressure of O2 and CO2 in the alveoli at rest? How
does heavy exercise affect these values?
16- Give the average partial pressures of O2 and CO2 in tissues at rest. How does
heavy exercise affect these values?
