Electrolytes Flashcards
1
Q
Cl-
A
Most prominent anion of the ECF. Kept very low inside cells
1
Q
Na+
A
Most prominent ECF cation. Makes up a huge fraction of osmolarity of blood plasma and ISF. Kept low inside cells
2
Q
Ca2+
A
98% stored in bones and teeth. So very low in all 3 compartments!
3
Q
K+
A
Most prominent intracellular cation. Makes up huge fraction of intracellular osmolarity. Kept very low in ECF
4
Q
HCO3-
A
Second most prominent anion of ECF. Very important buffer in blood plasma and ISF
5
Q
HPO42-
A
Most prominent intracellular anion. Kept very low in ECF
6
Q
Mg2+
A
Second most prominent intracellular cation, though 54% of body stores are in bones
