Question: Why are tears salty and different to water!?
Like the way they burn your face!?Www@Answer-Health@Com


Answers:
They are an ultrafiltrate of plasma (blood)!. As blood contains sodium (salt), so do tears!. When the plasma is filtrated to turn it into tears, not all of the sodium is reabsorbed!. Hence, tears taste salty!.

Tears do not contain urea!. They contain sodium chloride, potassium, albumin and glucose!. They also contain the immune cells lysozyme, and IgA, IgG and IgE!.Www@Answer-Health@Com

Tears aren't salty, its urea!. {a waste product from the body cells} Its just another way of getting it out of the body!.Www@Answer-Health@Com
