Document Summary
Solutes in the body are all ions and therefore carry net charges. Potassium of k+ is the major cation found inside cells. Sodium of na+ is the major cation found outside the cell in the extracellular fluid. Chloride or cl- is the major anion that is paired with na+ in the extracellular fluid. Phosphate or po4(2-) and negatively charged proteins are the major anions inside the cell or intracellular fluid. The same applies for the cations on the outside of the cell that do not have matching anions. Hence the positive net charge on the outside. This uneven distributions cause there to me and electrical disequilibrium. This is because they have equal amounts of protons, electrons and neutrons. When an electron is removed or added ions are formed. Ions important in the human body include na+,k+, and h+ For 1 positive ion theres a matching electron in a negative ion.
