essential study guide 5 - 10 Flashcards
functions of epithelia tissue
protection, absorption, filtration, secretion
bone functions
provide support, protection, serves as calcium reservoir
fat functions
protective cushion, insulation, stores energy.
tendons and ligaments functions
provide durable support
nervous tissue functions
sends and receives impulses
skeletal muscle functions
movement, breathing, facial expression, speech, controls urination.
cardiac functions
involuntary movement
smooth muscle functions
controls diameter of blood vessel
regeneration
replaced by same type of cell, most injuries to skin heal this way. Results in functional new cells.
fibrosis
replaced with scar tissue, doesn’t restore normal function. Muscle and nerve tissue heal this way.
List and describe the steps in the process of tissue repair.
- blood vessels bleed into wound.
- blood clot forms, forming scab, beneath the scab white blood cells ingest bacteria and debris.
- healthy tissue around wound sent nutrients, blood, proteins, this new tissue is called, granulation tissue. Fibroblasts in tissue secrete collagen which forms scar tissue.
- area around wound produces new epithelial cells, which migrate beneath scab, eventually the scab falls off, reveals new tissue
What are some of the health risks associated with increased abdominal fat
Heart disease, stroke, diabetes
describe structure of epiderms
stratum Basale is lowest layer and stratum corneum is level. contains keratin
structure of dermis
contains collagen fibers, reticular fibers, and elastin fibers
