              In the page shown below it talks about this lady who grows a new ear on her arm. Crazy I think, but Doctors at John Hopkins have attached a new ear to a patient that was grown on her own forearm. She is the first patient to receive a new procedure that uses rib cartilage to build an entirely new ear. After they build it up they placed it under her skin of her arm to grow. It seems to have been successful. She is going to have a normal looking ear build up with her own cells.

           In this video they talk about how people wouldn't have to wait for anymore transplants because doctors are building up human organs up with the persons own cells. It talks about how 20 people die each day waiting for a transplant and how there is over a hundred thousand people waiting to get a transplant. The organ has to come together and work together. Most body parts will be replaceable. In the video it show this rat who has a human ear on his back, which is gowning perfect cartilage.  It also talk about how your body won't reject it because its your own cells.

Epithelial Tissu

Stratified Cuboidal and Columnar, Stratified cuboidal is rare in the body, found in some sweat and mammary glands , usually two cell layers thick. Stratified columnar limited distribution in the body, is found in the pharynx, male urethra, and lining some glandular ducts, and occurs at transition areas between two other types of epithelia 

Stratified Squamous, Its a thick membrane composed of several layers of cells. Function in protection of underlying areas subjected to abrasion. forms the external part of the skin's epidermis, and lining of the esophagus mouth, and vagina. 

Simple Columnar, its a single layer of tall cells with oval nuclei, many contain cilia. You can usually find goblet cells in this layer. Function in absorption and secretion. Non ciliated type line digestive tract and gallbladder. Ciliated type line small bronchi, uterine tubes, and some regions of the uterus. cilia help move substances throughout internal passageway. 

Simple Cuboidal, single layer of cube like cells with large, spherical central nuclei. The function in secretion and absorption. Present in the kidney tubules, ducts and secretory portions of small glands, and ovary surface. 

Transitional, Has several cell layers, basal cells are cuboidal, surface cells are dome shaped, Stretches to permit the dissension of the urinary bladder,  Lines the urinary bladder, ureters, and part of the urethra.  

Simple Squamous, single layer of flattened cells with disc-shaped central nuclei and sparse cytoplasm.  The functions, diffusion and filtration. Present in the kidney glomeruli, lining of heart, blood vessels, lymphatic vessels, and serosae. 

Pseudo-statified Columnar,  single layer of cells with different heights; some do not reach the free surfaces, The nuclei are seen in different layers, Function in secretion and propulsion of mucus, It is present in male sperm- carrying ducts and trachea.
