The integumentary system also known as skin; surrounds the entire human body therefore being the largest organ

The skin and its annexes like hair, sweat glands, sebaceous glands, nails, etc. The main functions of the integumentary system is to function as a protective barrier, that keeps our body free from intrusion of foreign materials, microorganisms and prevents dehydration as well as protecting from desiccation and there are other functions also helps in elimination of waste products and in the regulation of our body tempeture.

The integumentary system is the body’s largest organ system. It comprises of the skin, hair, and exocrine glands. The integumentary system’s primary function is to protect the inner body from outside pathogens and harmful rays of light. It also helps to regulate body temperature and eliminate waste products from our bodies. While our skin seems simple from the outside, it is actually a complex network of different layers of cells. This research paper will talk about the integumentary system and its layers, how burn injuries are classified, and three dermatological diseases. The integumentary system has three distinct layers: the epidermis, dermis, and hypodermis. The epidermis is the most superficial layer of the skin that we see every day. It covers the entirety of our bodies to close off our inner organs from the outside world. The epidermis is avascular, meaning it does not contain any blood or blood vessels. Instead, it receives nutrients via diffusion from the dermis. The epidermis also has its own distinct layers. There are two different types of skin: thick and thin.

The skin is the largest and primary protective organ in the body, covering the body's entire external surface and serving as a first-order physical barrier against the environment. Its functions include temperature regulation and protection against ultraviolet (UV) light, trauma, protection from pathogens, microorganisms and toxins

The skin also plays a role in immunologic surveillance, sensory perception, control of insensible fluid loss, and homeostasis in general. The skin is also highly adaptive with different thicknesses and specialized functions in different body sites. This article will discuss the anatomy of the skin, including its structure, function, embryology, blood, lymphatic, and nerve supply, surgical and clinical significance. The epidermis is further divided into 5 layers on thick skin like the palms and soles (stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum, while in other places the epidermis has 4 layers lacking the stratum lucidum) (Someya T, Amagai M. 2019).

For the most part, thermoregulation is also accomplished by the dilation or constriction of heat-carrying blood vessels in the skin. Immune cells present among the skin layers patrol the areas to keep them free of foreign materials. Fat stores in the hypodermis aid in both thermoregulation and protection

Finally, the skin plays a role in the synthesis of vitamin D, which is necessary for our well-being but not easily available in natural foods.
