Chapter 4 Questions
1) John cannot expect a quick and uneventful recovery from his torn knee cartilage. In comparison with other tissues cartilage has a weak regenerative capacity. Because catprtilage is avascular and aging, the cells can lose their ability to divide which makes the healing process much harder.
2) Keratinized stratified squamous epithelium is better suited to protect the body's external surface than a simple columnar epithelium because it is composed of several layers instead of just a single layer and the cells are constantly being replaced, helping to protect against injury.
