The primary ECF cation is _____,and the primary ICF cation is _____. A) K⁺, Na⁺ B) K⁺, Ca²⁺ C) Ca²⁺, Na⁺ D) Na⁺, K⁺

Question

Quizplus · Accepted Answer

The primary extracellular fluid (ECF) cation is sodium (Na+), while the primary intracellular fluid (ICF) cation is potassium (K+). Therefore, option D is the correct choice as it includes Na+ as the primary ECF cation and K+ as the primary ICF cation. Options A, B, and C are incorrect as they do not have the correct pairing of Na+ and K+ as the primary cations for the ECF and ICF, respectively.
