Gas Exchange, Blood Chem & Resp. Rhythm, Flashcards
Alveolar Gas Exchange
the loading of oxygen and the unloading of CO2 in the lungs
Where is Oxygen carried to and what is the percentage
O2 is carried to the blood bound ot hemoglobin, 98.5%
What is O2 dissovled in
Plamsa 1.5%
How many forms does CO2 Transport
Three Forms: Carbonic Acid, Carboamino Compounds, Dissolved Gas
Carbonic Acid
90% of Carbon Dioxide reacts with water to form carbonic acid
Carboamino Compounds
5% binds to plasma protiens and hemogloibin
Dissolved Gas
5% carried in the blood as dissolved gas
Carbon Dioxide Loading (The Haldane Effect)
the lower the partial pressre of oxygen and saturation of it in hemoglobin, the more Co2 can be carried from blood
What unloads from hemoglobin molecules
Oxygen
Hydrogen Ion Conectrations
Strongly Influence Respiration
Carbon Dioxide Concentrations
Strongly Influence Respiration
Oxygen Concentrations
have little effect on respirtation
