Question

Indicate the various roles of the following ions: -cation in greatest concentration in the ECF A)Na⁺ B)K⁺ C)A^- D)Cl^-

Quizplus · Accepted Answer

Na+ is the cation in greatest concentration in the extracellular fluid (ECF), where it plays a crucial role in maintaining the osmotic balance, regulating the body's water content, and supporting nerve and muscle function.

B, C, and D are not the best choices because K+, A-, and Cl- are not the cations in greatest concentration in the ECF. K+ is primarily found inside cells, where it helps to maintain the cell's electrical charge and support enzyme function. A- is an anion, and it is not typically found in high concentrations in the ECF. Cl- is an anion that is found in roughly equal concentrations inside and outside cells, where it helps to maintain the electrical neutrality of cells and support fluid balance.
