Exam 13: The Respiratory System

The volume occupied by the conducting airways is known as the ____________________.

If the concentration of carbon dioxide at sea level (760 mm Hg) is 0.04 of 1.0%, the partial pressure of this gas is ____________________ mm of Hg.

The residual volume is the amount of air remaining in the lungs at the end of a normal expiration.

Slow, deep breathing is more effective for increasing alveolar ventilation than is rapid, shallow breathing.

The bronchioles are rigid, non-muscular airways, encircled by a series of cartilaginous rings.

A pneumothorax allows intrapleural pressure to equilibrate with atmospheric pressure.

Approximately what percent of carbon dioxide is transported in the blood dissolved in dissolved form?

The ____________________ serves as a common passageway for both the respiratory and digestive systems.

According to ____________________ law, at any constant temperature, the pressure of a gas varies inversely with the volume of the gas.

Boyle's law states that the pressure exerted by a gas varies directly with the volume of the gas.

The percent of hemoglobin saturation decreases as
