6612708733	Ventilation is also known as	Breathing	1
6612708734	The lower respiratory tract includes	All of the bronchial branches, lungs, and trachea	2
6612708735	Alveolar ventilation refers to the	Mvmt of air into and out of the alveoli	3
6612708736	The lungs are enclosed in ___ membranes	Pleural	4
6612708737	Type I alveolar cells	Allow rapid diffusion of gases through their membranes	5
6612708738	Surfactant	Helps prevent the alveoli from escaping	6
6612708739	Air entering the body is filtered, warmed and humidified by the	Upper respiratory tract	7
6612708740	If a student inhales deeply	Vital capacity	8
6612708741	In the lungs	Blood flow rate is higher and blood pressure is lower than in systemic circulation	9
6612708742	Histamines primary role in the respiratory sy is as a	Bronchoconstrictor	10
6612708743	Samuel suffers from cystic fibrosis	Thick secretions that exceed the ability of the resp track to remove them	11
6612708744	Breathing involves active inspiratory and expiratory mvmts called	Hyperpnea	12
6612708745	The resp rate times the tidal volume corrected for dead space is the	Alveolar ventilation	13
6612708746	In a condition known as pleursy theres excess flyid in pleural space. How would this affect pulmonary ventiliation	Breathing would be labored and difficult	14
6612708747	Of the factors that influence diffusion of respiratory gases, the most variable and therefore, important factor to consider is the	Concentration gradient	15
6612708748	The process by whixh dissolved gases are exchange btwn the blood and interstitial fluid is	Hypercapnia	16
6612708749	Lung pathology most likely to result from certain kinds of heart disease	Pulmonary edema	17
6612708750	Most CO2 in the blood is transported as	Bicarbonate ion	18
6612708751	Most of the oxygen transported by the blood is	Bound to hemoglobin	19
6612708752	Which of the following would make the oxygen hemoglobin curve shift right	Increased H+	20
6612708753	The most important chemical regulator of respiration is	Carbon dioxide	21
6612708754	An increase in the level od CO2 in the blood will	Increase the rate of breathing	22
6612708755	Protective reflexes of the lungs include	Coughing and bronchoconstriction	23
6612708756	For maximum efficiency in loading oxygen in the lungs	The temp should be slightly lower than normal body temp	24
6612708757	If the neural connections btwn the pons and medulla are severed	Pulmonary ventilation will decrease	25
6612708758	Jane lives in indiana	Decreased PO2 in alveolialveoli	26
6612708759	A molecule that blocks the activity of carbonic anahydrase would	Cause an increase in blood pH	27
6614671504	The chloride shift occurs when	Bicarbonate leaves rbcs	28
