Typically, engineered wood products are made from the same hardwoods and softwoods used to manufacture lumber. Sawmill scraps and other wood waste can be used for engineered wood composed of wood particles or fibers, but whole logs are usually used for veneers, such as plywood, MDF or particle board.
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.
Causes of mucus in stool. Dehydration and constipation can cause mucus from the colon to leave the body. This gives the stool the appearance of increased mucus. Increased mucus can also be a sign of illness, especially if inflammation occurs and the mucous membrane breaks down. This leaves the body more open to infection.
