Sunny Black Integumentary System The integumentary system is made up of the skin, hair, nails, sweat glands, nerves and oil glands. The skin is only a few millimeters thick, but by far the largest organ in the body. The normal person’s skin weighs about 10 pounds and has a surface area of about 20 square feet. The outermost layer of the skin makes up the epidermis. The epidermis is the most superficial layer of the skin and covers almost the entire body surface. The epidermis also does not contain any blood or blood vessels. The Subcutaneous tissue that attaches the skin to the muscle lies under the dermis, which contains blood vessels, nerve fibers, sweat glands and oil glands. The skin has a lot of functions that are critical to the well-being of the body including protection, storage, elimination, and sensory perception. Our skin tells us a lot about the general health of our body. As a person ages, changes become visible in the skin. Skin Lesions Injury and disease cause changes in skin structure, called lesions. A skin lesion is part of the skin that has an abnormal growth or appearance compared to the skin around it. Lesions can be single or multiple. There are two types of skin lesions primary and secondary. Primary skin lesions are abnormal skin conditions present at birth. Secondary skin lesions are the result of irritated or manipulated primary skin. These lesions can be caused by disease, trauma, wear and aging. When caring for patients with lesions, use standard precautions. Some examples of lesions or skin eruptions are nodules, which are firm papules, macules, which are flat lesions, papules, which are elevated, pustules, where the lesions contain pus, wheals, and vesicles that are small, clear, fluid-filled blisters,. Skin lesions can also be a result of systemic responses, such as communicable diseases or immune system problems.
