Quiet inspiration is the function of

During normal, quiet respiration, the amount of air exchanged between the lungs and atmosphere is called ________________ and has a volume of __________________ mL.

Functional residual capacity equals

Eupnea is a term used to describe

Under normal conditions, air in the atmosphere exerts a pressure of

Areas where gas exchange cannot take place are

All of the following are regulated processes associated with the functioning of the respiratory system except

Dalton's law is also known as

Temperature is the measurement of the motion of molecules

The largest amount of air that can enter and leave the lungs during respiration is termed total lung capacity (TLC)

Residual volume (RV) is the volume remaining in the respiratory tract after maximum expiration

The temporary cessation of breathing is termed apnea

It is not possible to exhale all of the air from your lungs

The ability of the lungs and thorax to stretch, referred to as [blank_start]compliance[blank_end], is essential to normal respiration.

Intrapleural pressure is always less, or negative with respect to alveolar pressure. The difference is called the [blank_start]transpulmanory[blank_end] [blank_start]pressure[blank_end].

Tidal volume multiplied by the respiratory rate yields the [blank_start]total[blank_end] [blank_start]minute[blank_end] [blank_start]volume[blank_end].

The constant alternation between inspiration and expiration is called the [blank_start]respiratory[blank_end] [blank_start]cycle[blank_end].

The basic rhythm of the respiratory cycle of inspiration and expiration seems to be generated by the [blank_start]medullary[blank_end] [blank_start]rhythmicity[blank_end] [blank_start]area[blank_end].

The term that means the same thing as breathing is

Which of the following does not occur during inspiration?

A young adult male would have a vital capacity of about

The amount of air that can be forcibly exhaled after expiring the tidal volume is knows as the

Which one of the following is correct?

Air in the pleural space of the thoracic cavity is called a pneumothorax

A deficiency of surfactant in premature infants is called SIDS

[blank_start]Tidal volume[blank_end]: normal exhalation volume [blank_start]Inspiratory reserve volume[blank_end]: approximately 3300 mL [blank_start]Pneumothorax[blank_end]: collapsed lung [blank_start]Physiologic dead space[blank_end]: increased in emphysema [blank_start]Oxygen pressure[blank_end]: Po2 [blank_start]Surfactant[blank_end]: reduces surface tension in lungs [blank_start]Apneusis[blank_end]: cessation of breathing [blank_start]Chemoreceptors[blank_end]: sensitive to changes in arterial CO2 and pH [blank_start]Hering-Breuer reflexes[blank_end]; helps control respirations [blank_start]CO2[blank_end]: respiratory stimulant
