Lynn Waldrop – Rebuild Your Body 2016 – Integumentary System
Description
The integumentary system, or skin, is the largest organ in the body. Besides the skin, it comprises the hair and nails as well, which are appendages of the skin. In humans, this system accounts for about 15 percent of total body weight. Skin and hair provide protection from harmful ultraviolet radiation and the skin guards against sunburn. It also waterproofs, cushions and protects the body from infection. The integumentary system excretes wastes and regulates body temperature. The skin is the body’s initial defense against bacteria, viruses and other microbes. Human skin color is determined by the interaction of melanin, carotene and hemoglobin.

More information about Medical:
Medicine is the science and practice of establishing the diagnosis, prognosis, treatment, and prevention of disease.
Medicine encompasses a variety of health care practices evolved to maintain and restore health by the prevention and treatment of illness.
Contemporary medicine applies biomedical sciences, biomedical research, genetics, and medical technology to diagnose, treat, and prevent injury and disease,
typically through pharmaceuticals or surgery, but also through therapies as diverse as psychotherapy, external splints and traction, medical devices, biologics, and ionizing radiation, amongst others.
Medicine has been around for thousands of years, during most of which it was an art (an area of skill and knowledge) frequently having connections to the religious and
philosophical beliefs of local culture. For example, a medicine man would apply herbs and say prayers for healing, or an ancient philosopher and physician would apply bloodletting according to the theories of humorism.
In recent centuries, since the advent of modern science, most medicine has become a combination of art and science (bth basic and applied, under the umbrella of medical science).
While stitching technique for sutures is an art learned through practice, the knowledge of what happens at the cellular and molecular level in the tissues being stitched arises through science.
