What law does this describe: The pressure of gas in your lungs is inversely proportional to the volume in your lungs.

Which muscles, when contracted, would increase the volume of air in the thoracic cavity?

Which pressure is the result of the natural tendency of the lungs to decrease their size (because of elasticity) and the opposing tendency of the thoracic wall to pull outward and enlarge the lungs?

During an allergic reaction, which of the following would aid respiration?

If the transpulmonary pressure equals zero, what will happen to the lung?

Which of the following pressures rises and falls with the phases of breathing but eventually equalizes with the atmospheric pressure?

Which of the following pressures must remain negative to prevent lung collapse?

Quiet inspiration is __________, and quiet expiration is __________.

In pneumothorax, the lung collapses because ______.

Which of the following is NOT a physical factor that influences pulmonary ventilation? alveolar surface tension airway resistance lung compliance partial pressure of oxygen in the air

Which form of CO2 transport accounts for the least amount of CO2 transported in blood?

Which of the following arterial blood levels is the most powerful respiratory stimulant?

What is the most common method of carbon dioxide transport?

Which of the following is the primary factor in oxygen's attachment to, or release from, hemoglobin?

What is the primary form in which oxygen is carried in blood?

what inhibits/reduces the respiratory rate

what conditions or scenarios increases the respiratory rate?

__________ pressure, the difference between the intrapulmonary and intrapleural pressures, prevents the lungs from collapsing.

Which of the following regions contains the opening of a canal that equalizes pressure in the middle ear?

Which of the following processes is NOT properly matched with its description? transport of respiratory gases: hemoglobin binds O2 internal respiration: O2 diffuses out of the blood pulmonary ventilation: bulk movement of gases external respiration: CO2 diffuses into the blood stream

The division between the upper and lower respiratory system is around the nasopharynx. true or false

Which of these structures is/are NOT properly matched with one of its/their functions? nasopharynx: conduct air toward and from the larynx pharyngeal tonsil: immune response nasal conchae: create turbulence for incoming air paranasal sinuses: surface for odor receptors

Jane had been suffering through a severe cold and was complaining of a frontal headache and a dull, aching pain at the side of her face. What regions are likely to become sites of secondary infection following nasal infection?

The adenoids normally destroy pathogens because they contain ______.

Select the correct statement about the pharynx. The pharyngeal tonsil is located in the laryngopharynx. The pharyngotympanic (auditory) tube drains into the nasopharynx. The laryngopharynx blends posteriorly into the nasopharynx. The palatine tonsils are embedded in the lateral walls of the nasopharynx.

The nose serves all of the following functions EXCEPT ________. cleansing the air warming and humidifying the air as the direct initiator of the cough reflex as a passageway for air movement

Which of the following plays a role in removing particles such as dust from inspired air?

The olfactory mucosal lining of the nasal cavity contains the receptors for the sense of smell. true or false?

The functions of the nasal conchae are to enhance the air turbulence in the cavity and to increase the mucosal surface area exposed to the air. true or false?

Nasal conchae mainly work on inhalation to warm and moisten air. They serve minor functions for exhalation. true or false?

What part of the larynx covers the laryngeal inlet during swallowing to keep food out of the lower respiratory passages?
