5 Jaundice yellow wliver damage - bile in bld
Jaundice Yellow skin discoloration caused by hyperbilirubinemia Anatomy of the liver An obstruction in the bile duct may lead to jaundice
6 Birthmark congenital disorder of dermal BV
Capillary Malformation (Port-wine Stain)
Vascular birthmarks are caused by enlarged small blood vessels just beneath the skins surface The most common are known as angels kissesldquowhen located on the forehead or eyelids and as stork bites
when they appear on the back of the neck
Most birthmarks are no risk to health

The epidermis the outer layer is burned Reddening occurs and swelling is possible
The epidermis is burned through and the dermis is also injured An intense red discoloring is accompanied by severe pain swelling and blisters
Full-thickness
3deg epidermis destroyed-skin graft
All layers of skin are burned through to the fat muscles and possibly to the bone There may be severe pain but sometimes extensive nerve damage results in little or no pain
