Skin, Skeletal, and Muscular Systems: the Integumentary System

The video explains that the skin, often overlooked as an organ, is the largest organ of the body, making up about 15% of body weight. It serves as a protective barrier, preventing microorganisms from entering and retaining body fluids. The skin plays a crucial role in excretion by removing waste through sweat, regulates body temperature, and protects against UV rays. It also synthesizes vitamin D. The skin is composed of two main layers: the epidermis, which is the outer protective layer, and the dermis, which contains connective tissue, blood vessels, and glands. The dermis supports various functions, including sensation and insulation.
