Exam 16: Respiratory System

The left lung has only two lobes, while the right lung has three.

At the end of a quiet inspiration, an additional volume of air can be inhaled. What is this additional amount of air called?

At a particular point in the circulation, the P _O2 of the blood is 104 mm Hg, and the P _CO2 is 40 mm Hg. Where is this location in the circulation?

Within a mixture of gases, the pressure created by each gas is called its __________ pressure.

Given the following respiratory values, what is this patient's vital capacity (VC)? Tidal volume = 550 mL Inspiratory reserve volume = 2800 mL Expiratory reserve volume = 1000 mL Residual volume = 1000 mL

Serous fluid in the pleural cavitytends to hold the visceral and parietal pleural membranes together.

Following a forceful expiration, some air always remains in the lungs. What is this volume of air called?

The left lung is larger than the right lung.

Microorganisms trapped in the mucus of the nasal cavity eventually end up in the __________.

The respiratory disease characterized by degeneration of alveolar walls is called __________.

By what process does gas exchange occur?

The glottis is the opening between the vocal cords.

What causes the change in pressure needed for normal quiet expiration?

Given the following respiratory values, what is this patient's inspiratory capacity (IC)? Tidal volume = 550 mL Inspiratory reserve volume = 2800 mL Vital capacity = 4500 mL Residual volume = 1000 mL

In which situation would the respiratory centers stimulate an increase in ventilation?

Advanced emphysema, involving the destruction of alveolar walls, results in difficulty exhaling. Why would this difficulty develop?

The potential space between the pleural membranes is called the pleural cavity.

After a full and complete inspiration, the volume of air that can be expelled from the lungsis called the __________.
