internal respiration is the exchange of gases between...
low temperature
the factors that increase the release of oxygen from hemoglobin in systemic capillaries include all of these except: high temperature, high PCO2, low PO2, low temperature
residual air
the air that remains in the lungs after the most forceful exhalation...
CO2, because if present in excess it lowers the pH of body fluids

carotid and aortic bodies
the receptors that detect a decrease in the oxygen level of blood are located in...
respiratory acidosis
if pneumonia decreases the exchange of gases in the lungs, the resulting pH imbalance is...
increasing the oxygen content of the air
the nasal mucosa has all of these functions except: warming incoming air, moistening incoming air, increasing the oxygen content of the air, sweeping mucus and pathogens to the pharynx
stuffed-up sinuses
all of this will increase physiological dead space except: fractured ribs, asthma, stuffed-up sinuses, tuberculosis
potential pleural space
anatomic dead space includes all of the following except: bronchioles, larynx, potential plueral space, nasal cavities
compliance
the expansibility of the lungs and chest wall is called...
