Chlorine is found in the human body, where it is the 10th most abundnace element. About one part in 1,000 of human physical makeup is chlorine.
The chloride content of human tissue is 1.1 g/kg body weight and the plasma concentration 98-106 mmol/l.
Chlorine in its chloride ion form is essential in the human body. There is about 95% of chlorine in the body, and at least 3 g of it is needed per day. Chlorine and chloride are non-toxic. The element itself, as chlorine gas, is very toxic.
In the body, chloride is necessary for the transmission of signals in the nervous system, regulation of the acid-base balance in body fluids, transport of carbon dioxide and exchange of bicarbonate in the ileum and large intestine.
