Mucus is a slippery secretion of the lining of various membranes in the body (mucous membranes). It is a viscous colloid containing antiseptic enzymes (such as lysozyme) and immunoglobulins. Mucus is produced by goblet cells in the mucous membranes that cover the surfaces of the membranes.
Normal Discharge. Most of the mucus in the urine originates from the lining of the urethra and the bladder. Both membranes are composed of epithelial cells. Once you urinate, some of the mucus flows with the urine though it is not visible because the refractive power of urine and mucus is almost equal.Urine originates from the kidneys where the proteins contained in mucus are produced. The urine carries the proteins on its way out of the kidneys.nce you urinate, some of the mucus flows with the urine though it is not visible because the refractive power of urine and mucus is almost equal.
