I. Tendons and Ligaments are comprised of dense regular connective tissue. II. Since ligaments do not have a considerable amount of blood or nerve supply, if they become injured their limited blood supply results in a longer recovery and healing period. After cartilage has been damaged some repair can be done by appositional growth, but after severe damage, cartilage is not repaired and a fibrous patch replaces the area. III. Inflammation is a localized tissues level response that tends to limit the spread of an injury or infection. The process of inflammation is initiated by the cells which are already in the tissue, which are mostly dendritic cells, macrophages, kupffer cells, and mastocytes. Histocytes and mast cells. Cells that prevent any infection can mostly be white blood cells. They are neutrophils, bands, eosinophils, basophils, monocytes and lymphocytes. Each of them will fight the infection in a different way. For example, neutrophils is one of the body’s main defense against bacteria. They kill the bacteria by ingesting them. Bands are immature neutrophils. When a person has parasites or an allergic reaction eosinophils kills it. Another white blood cell that fights allergies is the basophil by releasing histamine and heparin. Monocytes enter the tissue itself and ingest bacteria throughout the body. These cells can also destroy damaged dead cells. The monocytes and neutrophils can kill invading organism by squeezing the opening of the blood vessel. That kills bacteria by surrounding it and digesting them with enzymes. There is also a two phase that responds to injury and restores normal function. They are the vascular and cellular. To remove damaged tissue and make new tissue it does it by destroying or neutralizing harmful agents. Mixed with the repair process that replaces the damage tissues. The reaction of vascularized tissue to injury is...
