Tissue Repair

70
Q

The same kind of tissue replaces destroyed tissue and the original function of the tissue is restored.

A

Regeneration

71
Q

Connective is replaces destroyed tissue resulting in a scar and the original function is lost.

A

A

Step 1 Inflammation

73

Organization is restored to the blood supply, the blood clot is replaced with a granulation tissue, epithelium begins to regenerate, fibroblasts produce collagen fibers to bridge the gap, and the debris is phagocytized.

A

Step 2 Regeneration

74
Q

The scab will detach, fibrous tissue matures epithelium thickens and begins to resemble adjacent tissue, the results in a fully regenerated epithelium with underlying scar tissue.

A

Step 3 Fibrosis

75

Metabolic function

79
Q

The superficial layer/region, composed of epithelial tissue. Includes 5 layers of the Epidermis.

A

Epidermis Layer

80
Q

Consists of two layers that are composed of areolar and dense irregular connective tissue and is highly vascular (lots of vessels). Papillary layer which is the superficial zone of dermis, thin zone and allows for mobility of leukocytes if the epidermis breaks and is rich in small blood vessels. Reticular layer is deeper and much thicker layer that consists of irregular connective tissues. Stretch marks are tears in the collagen fibers caused from over stretching. Different types of connective tissue that include collagen, elastic and reticular fibers, fibroblasts.

A
