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.
The glands in a healthy vagina produce mucus. Normal vaginal mucus is slightly acidic and is comprised mostly of water, mucin and albumin, a water-soluble protein found in the tissue of mammals. Lactobacilli, beneficial bacteria, flourish in a normal vagina and help to maintain a healthy pH. The cervix also produces mucus.
