2. What is the Function of the Integumentary System? The main function of the integumentary system is to protect the body and all of it’s organs from harm, give you your sense of touch, and gives you the ability to adapt to temperature.

3. What are the Key Components of the Integumentary System and How do they work?

4. Epidermis At a tenth of a millimeter thick, the epidermis is an avascular region of the body, meaning that it does not contain any blood or blood cells. Instead, this region of the body receives nutrients from the underlying layers of the skin. Four primary functions: 1. Stores and produces keratin and proteins 2. Produces the pigment melanin, which protects you from UV light and sunburn (lack of these cells causes albinism 3. Detect and fight pathogens that try to enter the body 4. Has nerve endings to give you your sense of touch

5. Dermis The Dermis is the deep layer of skin under the epidermis. This region gives the skin it’s strength and elasticity, and is made of two layers, the papillary and reticular layers. Papillary- Layer touching the epidermis, contains nerves and blood vessels, also gives the epidermis it’s ability to detect temperature. Reticular- Thicker and deeper part of the dermis. Provides strength and elasticity, also contains more blood cells and nerve tissue.

6. Hypodermis The Hypodermis is a layer of loosely connected tissues, It serves as a flexible connection between the skin and the muscles and bones beneath. This layer allows the skin to move and stretch independently of the rest of the body, and contains fat deposits which store energy and insulate the body by trapping the heat from your muscles.

7. What personal habits are required to maintain health within the Integumentary System?

8. Are they’re any diseases related to the Integumentary system? If so what are known treatements? DiseasesTreatments RashesFor eczema hydrocortisone cream works well, but with other forms of rashes it can increase inflammation. BlistersMost Blisters will heal naturally. But, if you have an infected blister, or blisters that are painful or reoccurring you should seek medical advice. Athlete’s footThe treatment is in two parts. First, and most important is to make the infected area less suitable for the fungus to grow- keep it clean and dry. Second, your feet can be soaked in a homemade solution of dilute vinegar using four parts water to one part vinegar.

9. DiseasesTreatments SunburnsUsing a moisturizer that contains aloe vera or soy will help sooth sunburned skin. Just remember not to use lotions with scents, petroleum, benzocaine or lidocaine. Skin cancerFive standard professional treatments are used: surgery, radiation therapy, chemotherapy, photodynamic therapy, biologic therapy. Patients can also take part in a medical trial. AlbinismTreatment is to relieve symptoms. The main goal is to protect the skin and eyes from the sun. Sunscreen should have a high SPF level and sunglasses should have UV protection. AcneThere are many different treatment options. Some include prescribed oral medicine to balance hormones, and other treatments are face cleansers or lotions to be used daily.

10. Fun facts or ‘Super Human’ Abilities of the Integumentary System!  You have a whole new layer of skin every month.  Hair crows about 1 cm per month.  A grown adult man has about 20 square feet of skin.  Skin is the body’s largest organ.  Melanin, which is responsible for tanning, is also responsible for eye colour.

12. Organs Involved  The skin, in itself is essentially the integumentary system. But it is the skins appendages such as finger nails, hair and exocrine glands that complete the integumentary system.

13. Functions  Skin:  The skin’s main function in the integumentary system is to protect the rest of the components involved from things like damaging uv rays, water and abrasions Essentially, the skin protects the deeper tissues of the body..

14. Hair  Hair also protects from certain things like dust particles and also it helps to reflect uv rays from the thinner skin on our skuills.  Today eyelashes and eyebrows seem to be the most active contributors to protecting us because they catch things like dust and pollen from damaging our eyes.

15.  Fingernails and toenails grow from the root of the skin to reinforce it’s boundaries and to protect the more delicate skin underneath of them.  Nails are made up of a hard protein called keratin which is dead. Keratin is also the same protein that makes th rattling sound in a rattlesnake. Nails

16. Exocrine Glands  Ecocrine glands are glands that secrete their products into ducts (pores). They are the counterparts to endocrine glands which secrete their products back into the bloodstream.  Typical exocrine glands include sweat glands, salivary glands, mammary glands and many glands of the digestive system.

17. Supporting the Integumentary System  Vitamin A rich foods aree needed for keratin synthesis ( the process through which hair and nails create themselves) to take place.  Also water helps to flush toxins fromn your body which are sweat out by exocrine glands in the dermis. While not exactly protecting your integumentary system, it does allow it to do it’s job more effectively.
