It is made up of the osmotic effects of serum sodium, potassium, glucose, and urea. However, urea traverses membranes relatively freely and thus does not contribute to the serum tonicity that is also called the effective osmolarity, which is calculated by using the following formula: banzai aqua adventure water park
