Anatomical lubricant is produced naturally by the human organism, though it may also be manufactured artificially. Synovial liquid constitutes one anatomical lubricant which is secreted by the human body where the joints are located. Vaginal lubrication is another anatomical lubricant which is produced to lubricate the vagina during sexual intercourse. Artificial lubricants are used in medicine to facilitate the entry of an object into an orifice. Such is the case during an endoscopy or the taking of a temperature.
