Answer:
Substances known as electrolytes are found in blood which includes sodium and potassium.
Step-by-step explanation:
Electrolytes are electrically charged particles and they help in moving nutrients into the cell and removing waste particles out of the cell. Other functions of electrolytes include maintaining the salt level as well as pH level of the body.
The electrolyte potassium is present in small quantities in the fluid part of blood, namely plasma.
Regulating body muscle contraction is the main function of potassium. The fluid region outside cells contains a major portion of sodium which maintains the water balance of the body.
