transport of oxygen & Carbon dioxide Flashcards
1
Q
what percentage of oxygen is carried in the blood plasma
A
3%
2
Q
where is 97% of oxygen found
A
carried in hemaglobin molecules found in RBC
3
Q
what will happen if oxygen is low in a part of the body
A
oxyhemaglobin will break dowin into hemaglobin and oxygen which releases oxygen to parts of the body with low O2
4
Q
what is it called when carbon dioxide binds to hemaglobin
A
carbaminohemaglobin
5
Q
what happens when carbon dioxide diffuses into the plasma
A
some CO2 dissolves into plasma, some combines with hemaglobin but most of it is converted into bicarbonate ions
6
Q
what percentage of CO2 is dissolved in plasma
A
7-8%
7
Q
what percentage of CO2 is transported in carbminohemaglobin
A
22%
8
Q
what percentage of CO2 is transported in bicarbonate ions
A
70%
