Answers:
First, let's look at skin and what's under it!.
Skin is made up of two layers:
The epidermis is the outer layer !.!.!. it's what you see!. There are various kinds of epidermal cells!. Keratin is the outer thin layer of skin cells, which are continually dying and flaking off, to be replaced by new cells from below!. Also in the epidermis are melanocytes, which produce colour to protect you from UV rays!. There are also sensory receptor cells that provide information about touch and other senses!.
The epidermis itself has four layers, except on your palms and the soles of your feet where there are five; the extra outer layer of skin cells provides added protection!.


The dermis is the next layer down, and it's is full of nerves, blood vessels, hair follicles, oil and sweat glands!. The lower level of the dermis contains dense connective tissue made from interlacing collagen fibers, which provide strength!.

Below all this is a layer of fat!.


When you get a burn, the severity of the injury is determined by how many layers get destroyed!. Burns are classified as first, second and third degree, with each being progressively worse!.

First degree burns are superficial!. They affect only the epidermis, and cause reddening and a little swelling!. The red area will turn white when you press on it!. The skin over these burns peels off after a few days, and the burned area is mostly healed after a week or so!.

Second degree burns are deeper, causing damage to the epidermis and partail damage to the dermis, including the blood vessels!. They cause blisters, and are painful!. The fluid inside a blister is called serum!. It's a watery liquid that leaks from nearby tissues and blood vessels that have been destroyed!. This blister filled with serum provides pillow-like protection for the skin beneath it!. Second degree burns take several weeks to heal completely!. Eventually the fluid inside the blister is absorbed by the body,and the dead blister skin will drop away, leaving new skin underneath!.
From visitor Dan Pestana, we received futher information about serum:

"Serum is the liquid part of the blood, normally a golden yellow color, that is left when the blood cells are removed!. It is comprised of water, as well as a very high content of various proteins!. These include:

- albumin: a protein that aids in the proper retention of water in the bloodstream
- globulins: which are antibodies
- other useful proteins
Serum accumulates on burns, scrapes, or impetigo sores and as it dries, produces a characteristic honey-golden crust"!.


Third degree burns are ones that cause extensive damage to the epidermis and dermis, destroying blood vessels, nerves and glands as well!. The outer layer of keratin is gone, allowing moisture to escape; death from dehydration can follow extensive 3rd degree burns!. If untreated, infection of the exposed under-layers can also result!.

If enough blood vessels are damaged, blood clots will form, creating a scab!. As the wound heals, remaining epidermis cells begin to produce new cells at a fast rate!. Eventually the wound fills in, but if the wound is deep, there will be a scar!. Scar is tissue composed of collagen fibers arranged to provide maximum strength!. Because a scar does not contain nerves, it will feel numb!. Complete healing can take a month or more!.

Since severe third degree burns leave scars, they are often treated by applying skin grafts!. A skin graft is a very thin layer of skin that is cut from an unburned area and put on the burned area!.Www@Answer-Health@Com

the liquid inside the blister acts like a cushion while the damaged skin heals!. whatever you do, dont burst it!. when you burst a blister, its then like an open wound and prone to infectionWww@Answer-Health@Com
