Chapter 15 Respiratory
the upper respiratory tract includes of the following expect: nasal cavities, larynx, primary bronchi, nasopharynx
during swallowing, the larynx is covered by...
during swallowing, the nasopharynx is covered by...
the trachea is kept by which tissues?
in the nasal cavities and reachea, mucus and pathogens are swept to the pharynx by...
the of the oharynx that is a passageway for the air only is the..
inhaled air passes from the trachea to the...
cartilage supports and keeps open all of these structures except the...
the serous fluid between the pleural membranes keeps the membranes together and...
hilus on the medial side
the primary bronchi and the pulmonary blood vessels enter the lung at...
the tissue fluid that lines the alveoli is important to...
within the alveoli, surface tension is decreased and inflation is possible because of the presence of...
medulla and pons
the respiratory centers in the brain are located in....
diaphargm, which moves down
during inhalation, the thoratic cavity is enlarged from top to bottom by contraction of the...
high PO2 and high PCO2
in the alveoli, the partial pressures of oxygen and carbon dioxide are...
bronchial tree and alveoli
intrapulmonic pressure is the air pressure within the...
irritants on the muscosa of the larnyx are removed by...
bonded to hemoglobin in RBCs
most oxygen is transported in the blood
as bicarbonate ions in the plasma
most carbon dioxide is transported in the blood
systemic capillaries and bloody tissues
internal respiration is the exchange of gases between...
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
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
the gas that is the most important chemical regulator of respiration
carotid and aortic bodies
the receptors that detect a decrease in the oxygen level of blood are located in...
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
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
the expansibility of the lungs and chest wall is called...
increase to exhale more CO2
the compensate for metabolic acidosis, respiations will...
