Answer» Who said Lips are a wastegial organ. In human body , nothing is wastegial organ.Lips have many purpose:1. During Food intake2. During articulation or speaking3. A tactile organ4. An erogenous zone.\xa0Clinical significanceAs an organ of the body, the lip can be a focus of disease or show symptoms of a disease:\tOne of the most frequent changes of the lips is a blue coloring due to\xa0cyanosis; the blood contains less oxygen, and thus has a dark red to blue color, which shows through the thin skin. Cyanosis is the reason why corpses sometimes have blue lips. In cold weather cyanosis can appear, so especially in the winter, blue lips may not be an uncommon sight.\tInflammation of the lips is termed\xa0cheilitis. This can be in several forms such as\xa0chapped lips\xa0(dry, peeling lips),\xa0angular cheilitis\xa0(inflammation of the corners of the mouth),\xa0herpes labialis\xa0(cold sore, a form of\xa0herpes simplex) and\xa0actinic cheilitis\xa0(chronically sun damaged lips).A child with\xa0cleft lip\tCleft lip\xa0is a type of\xa0birth defect\xa0that can be successfully treated with surgery.\tCarcinoma\xa0(a malignant cancer that arises from epithelial cells) at the lips, is caused predominantly by using tobacco and overexposure of sunlight. Alcohol appears to increase the carcinoma risk associated with tobacco use. It is most often a diffuse and often hyperkeratinised lesion, occasionally has the form of nodules and grows infiltratively, and can also be a combination of the two types. It more often occurs at the lower lip, where it is also much more malign. The lower lip carcinoma is exclusively\xa0planocellular carcinoma, whereas at the upper lip, it can also be\xa0basocellular carcinoma.\t
