    These reactions could lead to polyp formation and may be triggered by allergy, infection or inflammatory mediators. Alteration in the mucous glands is another factor that may lead to the development of nasal polyps through a break in the epithelium followed by bulging of the submucosa through to polyp development. Another theory is that neurovascular changes may contribute to polyp formation although less work has been conducted in this area. Lack of blood flow into the sinus region

    Fibroblast The fibroblast is the large cell type of the dermis. These cells are responcible for the formation of procollagen and elastic fibers. Procollagen is terminally cleaved by proteolytic enzymes into collagen which aggregates and turned into cross-linked. These tightly cross-linked collagen fibers allow tensile strength and resistance to shear and other mechanical forces.(9,10) Collagen makes up 70% of the weight of the dermis, primarily Type I (85% of the total collagen) and Type III (15%

    pseudostratified ciliated columnar epithelium while the alveoli are lined with simple squamous epithelium? The trachea is lined with pseudostrastified ciliated columnar epithelium because the globlet cells that are there produce sticky mucous to coat the inner lining and catch any debris in inhaled air before it gets to the lungs. The columnar cells have cilia that push mucous away from the lungs. The alveoli are lined with simple squamous epithelium because the very thin epithelium will facilitate the diffusion
