Tissues - Damage and Repair

tissue membrane

a thin sheet/layer of tissue that covers a structure or lines a cavity

epithelium and connective

most tissue membrane are blank or blank

cutaneous, mucous, serous, and synovial

four tissue membranes in the body

mucous membrane

lines cavities that open to the outside of the body

stratified epithelium, basement membrane, thick layer of loose connective tissue

mucous membranes consist of…

nasal and oral cavities, urethra, anus, and vagina

where do we find mucous membranes?

serous membrane

lines cavities that do not open to the exterior of the body

simple squamous epithelium, basement membrane, and thin loose layer of connective tissue

serous membranes consist of…

secrete serous fluid and lubricate surface of membranes

function of serous membranes

synovial membranes

line the cavities of freely movable joints

connective tissue, no epithelium

synovial membranes are made up of…

secrete synovial fluid to reduce friction and allow smooth joint movement

function of synovial fluid

the inflammatory response

when you damage something, blank initiates the healing

immune response

delayed, second response to injury

redness, heat, swelling, pain, and disturbance of function

five symptoms of swelling

chemical mediators releasing

first part of inflammation includes…

signal to the body that damage has occurred

when chemical mediators are released, they…

tissue swells/edema

second part of inflammation

inccreases

when the tissue swells, blood flow …

oxygen and nutrients and antibodies to fight infection

when tissue swells, blood stream brings blank and blank

helps dilute toxins secreted by bacteria

tissue swelling…

immune cell recruitment/migration

third part of swelling

neutrophils migrate from blood stream into tissue, and bacteria is phagocytized

during immune cell recruitment/migration

regeneration or replacement

tissue repair can occur by blank or blank

regeneration

new cells are the same type as those restored, and normal function is restored

replacement

a new type of tissue develops, which produces a scar and causes loss of some tissue function
