Scars are areas of fibrous tissue (fibrosis) that replace normal skin after injury. A scar results from the biological process of wound repair in the skin and other tissues of the body. Thus, scarring is a natural part of the healing process. With the exception of very minor lesions, every wound (e.g., after accident, disease, or surgery) results in some degree of scarring. An exception to this are animals with complete regeneration, which regrow tissue without scar formation.
Scar tissue is composed of the same protein (collagen) as the tissue that it replaces, but the fiber composition of the protein is different; instead of a random basketweave formation of the collagen fibers found in normal tissue, in fibrosis the collagen cross-links and forms a pronounced alignment in a single direction. This collagen scar tissue alignment is usually of inferior functional quality to the normal collagen randomised alignment. For example, scars in the skin are less resistant to ultraviolet radiation, and sweat glands and hair follicles do not grow back within scar tissues. A myocardial infarction, commonly known as a heart attack, causes scar formation in the heart muscle, which leads to loss of muscular power and possibly heart failure. However, there are some tissues (e.g. bone) that can heal without any structural or functional deterioration.
I'm living down by Linbrook bowl where things don't look so pretty
Cast your eyes up on the I-5 and Welcome to my city
where tourist's don't drive, out to the west side where no one walks alone
Fireworks that glitter ain't gold and Priced out of a home
What was once the knife's turning to gun
A coat of cheap new paint over the slum
The Neon's disappearing one by one
Remodel - remodel - and take out all my fun
I walk past Linda's and Chain, but nothing's going on
Feels like I could go insane, Mariachi blaring on
Well, Mickey Mouse don't love the poor when they're knocking on his door
Is it any wonder I can't take it anymore?
We're begging for a capitalist catastrophe
Drive past the unlucky ones you see
Rats in tunnels under Crescent street
Now living at the top of the palm tree
Follow me, I'm getting out
I don't want to stick around
Pack my bags forget this town
