Prev NEXT The outermost layer of your skin, the epidermis, is the thin, tough part of your body that acts like a protective shell.
Purpose To develop an understanding of the science behind keeping skin healthy, including how it functions to protect the body and what can be done to protect skin cells from mutations caused by excessive sun exposure.
Context This lesson is part of the Skin Deep Projectwhich examines the science behind skin. For more lessons, activities, and interactives that take a closer look at the science behind skin, be sure to check out the Skin Deep Project page. This lesson is the first of two lessons about skin cancer using the SCI: Skin Cancer Investigation interactive.
In the first lesson, Skin Cancer 1: Exposing Healthy Skin to the Sun, students are introduced to the science behind keeping skin healthy including how it functions to protect the body and what can be done to protect skin cells from mutations caused by excessive sun exposure.
Types, Prevention, and Detection explores what happens when healthy skin cells mutate and grow uncontrollably, leading to skin cancer. This lesson continues use of the Skin Cancer Investigation interactive by beginning with "Skin Cancer: They may be unaware that it is the largest organ in their body.
The human adult is covered in about 22 square feet of skin. However, students are usually very aware of skin problems, particularly acne and other blemishes as they relate to physical appearance. High-school students may be particularly curious about the causes and prevention of skin problems but have little knowledge about skin cancer.
The Skin Deep Project takes advantage of this curiosity by introducing students in grades 6 through 12 to the science of skin, its role in protecting the body from invading microbes, regulating temperature, and sensing the environment. They will learn about the layers of healthy skin and what happens when healthy cells mutate and grow uncontrollably.
In addition to the interactive, students using this lesson will access the online book The Science Inside the Skin for in-depth information about the science of skin.
It is important for students to understand the basics about cells and cell division. Normal skin constantly produces new cells to replace older, dead cells. New skin cells result from cell division, which is normally a regulated process controlled by DNA.
At times, there is a breakdown in the process when new skin cells are produced unnecessarily or dying, damaged cells do not die. This breakdown can be because of DNA damage.
Exposure to the sun without adequate protection can damage DNA in skin cells. The UV rays in sunlight cause this damage.The skin is cleverly designed to perform in helping the skin acting as a physical, chemical and physical barrier for the body.
The physical barrier acts as a protective cover to protect us from the environment i.e. pathogens, physical abrasions and radiation from the sun. Yet it is known to be one. How Does Skin Prevent Disease? by JESSICAJOHNSON Aug.

of skin, and it is the largest organ in your body. Your skin serves many purposes, but one of its major functions is to protect the body from infectious organisms, such as parasites, bacteria or viruses.
WHAT IS ECZEMA? Eczema is a category of skin disease that is characterized by inflammation, itching, dry scaly skin, and in severe cases, small fluid filled blisters and insomnia 4 / How Does The Skin Act As A Barrier The skin is cleverly designed to perform in helping the skin acting as a physical, chemical and physical barrier for the body.
how the does the skin act as a barrier The skin is cleverly designed to perform in helping the skin acting as a physical, chemical and physical barrier for the body. The physical barrier acts as a protective cover to protect us from the environment i.e. pathogens, physical abrasions and radiation from the sun.
How does the skin act as a Physical Barrier? It is exposed directly to microorganisms and other toxic substances, and is subject to objects that touch, abrade and ter it.
Sunlight, heat, cold, and chemicals can damage as well as cuts, scrtaches, insect and animal bites, burns and other wounds can disrupt the continuity of the skin and make it volnerable to infection.
