Exam 27: B: Physiology of the Respiratory System

The structural designs of alveoli and capillaries in lung tissue are such that they facilitate oxygen diffusion.List examples that support the concept that structure determines function.

A drop in the body's production of carbonic anhydrase would hinder the formation of:

Why would a collapsed right lung,due to a pneumothorax,also collapse the left lung?

The major form by which carbon dioxide is transported in the circulatory system is:

Which of the following constitutes total lung volume?

Which type of breathing is characterized by repeated sequences of deep gasps and apnea,and is usually seen in people with increased intracranial pressure?

Which of the following would have the greatest accelerating effect on the dissociation of oxygen from hemoglobin?

Define pneumothorax,and discuss its potential effect on respiration.

The symbol HbNCOOH- is used for:

Match each type of breathing with its corresponding definition. -repeated sequences of deep gasps and apnea; indicates increased intracranial pressure

Internal respiration can be defined as:

If anything decreases alveolar PO₂,how does that affect the alveolar-blood oxygen pressure gradient?

Identify and describe four nonrespiratory breathing reflexes.

External respiration can be defined as:

Dalton law states that the partial pressure of a gas in a mixture of gases is _____ to the total pressure of the mixture.

The vital capacity is equal to the sum of the:

Match each type of breathing with its corresponding definition. -temporary cessation of breathing at the end of a normal expiration

The inspiratory center is located in what part of the nervous system?

Match each type of breathing with its corresponding definition. -decrease in pulmonary ventilation that results in elevated blood levels of carbon dioxide

Explain Dalton law as it relates to the movement of oxygen from the lungs into the circulatory system.
