FOCUS HERE: Resp: Gas Exchange Flashcards
describe the process of breathing and gas exchange from the inhalation of o2 to exhalation of co2
whats the difference between PX and FX
what is daltons law of partial pressures
PB is normally:
how do we factor in humidified air when trying to find partial pressures
how to find partial pressure
why do Po2 and Pco2 go down when air is humidified in the respiratory tract
when po2 is equal between air and water will the concentrations be equal? why or why not
why does more co2 dissolve in water at the same partial pressure as oxygen
what is ficks law of diffusion
where does oxygen cross into
where does carbon dioxide cross into
how is gas exchange impacted in emphysema
how is gas exchange impacted in fibrotic lung disease
how is gas exchange impacted in pulmonary edema
how is gas exchange impacted in asthma
what does low arterial po2 cause
what does a low arterial po2 mean
what is the po2, pco2 in alveolar air
what is the po2, pco2 in arterial blood
what is the po2, pco2 in tissues
what is the po2, pco2 in venous blood
what is the po2, pco2 in atmospheric air
explain how o2 goes from the alveoli into the blood
explain o2 conc differences in plasma vs rbc
describe the structure of hemoglobin - how many chains? what is the structure of the heme groups?
describe the oxygen hemoglobin dissociation curve. what are the relative hb saturation by o2 at alveoli, tissues
how does ph impact hemoglobin saturation
how does temperature impat hemoglobin dissociation
how does pco2 impact hemoglobin dissociation
desrcibe the hemoglobin dissociation curve of fetuses. why is it different
describe how carbon gets transported from cells into blood cells, into plasma
desrcibe how co2 from rbcs gets to the alveoli
describe the haldane effect: what happens as po2 increases? why?
