Compliance, in the respiratory system, refers to the ease with which one can expand the lungs and the thorax. Which of the following situations would decrease complance.
fluid accumulation in lungs
full extension of intercostal muscles
During inspiration, the expansion of the lungs causes:
cohesion of visceral and parietal pleura
an increase in intrathoracic pressure from about -6 to -4 mmHg

Anemia results from a decrease in the number of red blood cells. Although red blood cells only carry about 15% of the CO2 produced by cellular respiration, why would an individual with anemia report shortness of breath?
Fewer red blood cells to convert CO2 to HCO3- + H+ in the blood will result in a deceased pH and increase ventilation, or shortness of breath
Fewer red blood cells convert HCO3- into H+
What is the function of bronchi?
Transport air from nose to lungs
Transport air from trachea to lungs
Transport air from alveoli to blood
Transport air from lungs to alveoli
The respiratory epithelium of the conducting airways consists of
ciliated squamous epithelium
pseudostratified ciliated columnar epithelium
simple squamous epithelium
moist cuboidal epithelium
What must happen in order for air to be drawn into the lungs?
The diaphragm contracts and flattens while the intercostal muscles expand the rib cage, causing an increase in space within the chest cavity. The increase in space means the air pressure is lower inside than outside, causing a rush of air into the lungs.
The diaphragm relaxes to flatten out and allows the
lungs to expand. The intercostal muscles then contract to further expand the
thoracic cavity. This creates a difference in air pressure and air rushes into
the lungs.
Smoking can cause a form of Chronic Obstructive Pulmonary Disease (COPD) referred to as emphysema, a serious lung disease. How do smoking and emphysema impact the respiratory system’s ability to exchange gasses?
The surface area needed for gas exchange in alveoli is decreased.
Cilia are prevented from removing debris from the respiratory system.
