Class Summary - Today we finished off the chapter talking about burns. 1st degree burns do not pass the epidermis and heal quickly with peeling skin. 2nd degree burns touch some of the dermis and blister. 3rd degree burns damage the dermis and the accessory organs in the dermis. 4th degree burns damage down to the bone. Burns are measured not only by depth but also by extent of the burn. We use the 'rule of 9s' to figure out what percentage of the body is affected by the burn. We talked about the purpose of the skin to maintain the body's homeostasis and also talked about the effects of aging on the integumentary system.
Homework - The Integumentary System Test is on Tuesday
Objectives - Students will name and describe four types of burns with regard to depth. Students will describe how the rule of 9s is used to estimate the extent of a burn. Students will describe changes that occur in the integumentary system when we age. Students will list and discuss the functions of the skin that contribute to homeostasis.
