All of the following statements refer to events of tissue repair. Put the events in proper numbered order according to the sequence of occurrence. The initial event, the injury, is already indicated as number one.

Adipocytes contain a fat-filled vacuole that can fill or empty, causing the cell to gain or lose volume.
Since mature adipocytes do not divide, how can adults gain weight?
Tendons are composed of dense regular connective tissue, which consists of densely packed, parallel connective tissue fibers. This type of tissue has relatively few cells and vascular supply is poor; consequently, repair is slow. Because of the structure of the tissue, surgical repair can be compared to attempting to suture two bristle brushes together.
Tendon tears or breaks are difficult to repair both physiologically and surgically. Why?
In epithelial tissue the cells are packed together very tightly. Epithelial tissue is avascular. Epithelial tissue has three cell types that cover or line things and make tubes. Epithelial tissue has no fibers and it tends to be polar. Connective tissue has cells spaced far apart and is highly vascular (except cartilage). The cells of connective tissue vary greatly in shape and size. Connective tissue glues other tissues together and has three fiber types. Connective tissue tends to be nonpolar. Connective tissue has a large amount of ground substance; epithelial tissue does not.
How is epithelial tissue the opposite of connective tissue?
Stratified squamous epithelium changes cell shape from the basement membrane to the surface. At the basement membrane the cells tend to be columnar or cuboidal and flatten out as they work their way to the surface. Transitional epithelium has cells that are pretty much the same shape from the basement membrane to the surface. The surface cells are generally the largest cells. The cells change their shape according to the pressure applied.
What is a simple method of telling the difference between stratified squamous epithelium and transitional epithelium?
Blood does not give mechanical support, its matrix is fluid, the cells are loose, the fibers are soluble, it carries nutrients, waste products, and other substances and attaches to several gasses.
How is blood unique among connective tissues?
The ectoderm produces skin, the nervous system, and all tubes opening to the outside. The mesoderm produces muscles and connective tissue. The endoderm produces all internal organs.
