The Skin, its structure, function and response to injury - Section 34.1

The video tutorial covers the structure and function of the skin, including its protective role, the types of tissues it contains, and the layers of the skin. It explains the functions of the skin, such as temperature regulation, sensory reception, and vitamin D production. The repair process of the skin after injury is also discussed, highlighting the importance of clot formation and new cell growth.
