Why does damaged cartilage heal slowly?

Cartilage is avascular, so materials needed for repair must diffuse from surrounding tissue.

Match the following epithelial tissues to their correct descriptions. -Pseudostratified ciliated columnar epithelium -Ciliated simple columnar epithelium -Transitional epithelium -Simple squamous epithelium -Simple cuboidal epithelium -Nonciliated simple columnar epithelium -Stratified cuboidal epithelium -Keratinized stratified squamous epithelium A. A fairly rare type of epithelium that has a mainly protective function B. Contains a single layer of flat cells; found in the body where filtration (kidney) or diffusion (lungs) are priority processes C. Contains cells with microvilli and goblet cells; found in linings of the digestive, reproductive and urinary tracts D. Contains cells that are all attached to the basement membrane, although some do not reach the surface; those cells that do extend to the surface secrete mucus or contain cilia E. Found in the urinary bladder; contains cells that can change shape (stretch or relax) F. Lines the lower respiratory tract and uterine tubes; wavelike motion of cilia propels materials through the lumen G. Found in the superficial part of skin; provides protection from heat, microbes and chemicals H. Contains cube-shaped cells functioning in secretion and absorption
