Question 1

One of the basic tenets of physiology is that function of a system follows its structure. Describe the anatomy of the conducting zone of the respiratory tract, including how those structures contribute to the function of the lungs.

Accepted Answer

The answer of One of the basic tenets of physiology...

Question 2

Pressure is the driving force for the movement of air into and out of the lungs. However, the development of pressure and the movement of air are modified by the resistance of the airways. Describe how airway resistance can alter the movement of air into the lungs, including asthma in the discussion.

Accepted Answer

The answer of Pressure is the driving force for the...

Question 3

The generation of the pressure responsible for the movement of air follows Boyle's Law. Describe how Boyle's Law relates to pressure development in the lungs, and how that determines inspiration and expiration.

Accepted Answer

The answer of The generation of the pressure responsible for...

Question 4

Pressure is the driving force for the movement of air into and out of the lungs. Describe the structure of the thoracic cavity and how that structure is involved in creating the pressures that are important for the movement of air into the lungs.

Accepted Answer

The answer of Pressure is the driving force for the...

Question 5

The bronchus diverges into two lobes, the left and right lungs.

Accepted Answer

Question 6

One of the basic tenets of physiology is that function of a system follows its structure. Describe the anatomy of the respiratory zone of the respiratory tract, including how that structure contributes to function.

Question 7

The conducting zone adjusts the temperature and humidity of the air entering the respiratory tract.

Accepted Answer

The structures in the conducting zone (such as the nasal cavity, trachea, and bronchi) can help adjust the temperature and humidity of the air before it reaches the respiratory zone where gas exchange occurs. This is important for protecting the delicate tissues of the lungs and ensuring efficient gas exchange.

Question 8

Pressure is the driving force for the movement of air into and out of the lungs. However, the development of pressure and the movement of air is modified by the compliance of the lungs. Describe how lung compliance can alter the movement of air into the lungs.

Accepted Answer

The answer of Pressure is the driving force for the...

Question 9

Residual volume can be measured because the lungs are able to collapse under experimental conditions.

Accepted Answer

Residual volume cannot be directly measured by spirometry because the lungs cannot fully collapse, leaving a volume of air that remains in the lungs even after maximal exhalation.
