Transpiration is the principal factor.
The human body contain approx. 0,4 % sodium chloride.
Sodium Chloride
The body doesn't produce sodium chloride.
The human body contain approx. 4 % sodium chloride.
All salts soluble in water can exist also in organisms.
Because they form the compound Sodium Chloride NaCl which the human body requires in very small amounts. Sodium Chloride is poisonous if too much is consumed, especially by infants.
Both sodium and chloride play important roles in the human body. Sodium is involved in the electrical processes that allow our nerves to function. Chloride aids in some cellular processes.
sodium chloride, glucose, amino acids, nucleic acids, triglycerides
The human lethal dose of sodium chloride (LD50) is 3 g NaCl/kg body.
Sodium chloride has got electron configuration of 2,8,1. Potassium chloride has got electron configuration of 2,8,8,1. They behave identically in almost all the chemical reactions. But then you have potassium chloride molecule inside the cell. You need to have sodium chloride molecules out side the body cell to make them survive. If you get intravenous injection of sodium chloride, nothing will happen to you. If you give intravenous injection of potassium chloride, you will die instantly. How body cells recognize the difference between sodium chloride and potassium chloride in no time is the big question mark.
From the added sodium chloride in foods.
An electrolyte is a liquid that contains ions. The body fluids such as blood, plasma and interstitial fluid has a high concentration of sodium chloride, which is broken down into sodium ion (Na+) and chloride ion (Cl-).
