The integumentary system is the set of organs forming the outermost layer of an animal's body. It comprises the skin and its appendages, acting as a physical barrier between the external environment and the internal environment that it serves to protect and maintain. The integumentary system includes hair , scales , feathers , hooves , and nails.
Although you may not typically think of the skin as an organ, it is in fact made of tissues that work together as a single structure to perform unique and critical functions. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue Figure 1. The deeper layer of skin is well vascularized has numerous blood vessels. It also has numerous sensory, and autonomic and sympathetic nerve fibers ensuring communication to and from the brain. Figure 1.
Nurses need to understand the skin and its functions to identify and manage skin problems. This article comes with a self-assessment enabling you to test your knowledge after reading it. Nurses observe the skin of their patients daily and it is important they understand the skin so they can recognise problems when they arise. This article, the first in a two-part series on the skin, looks at its structure and function. Citation: Lawton S Skin 1: the structure and functions of the skin. Nursing Times [online]; , 12,

The human body is protected by the skin, a continuous covering which at level of the natural orifices eyelids, nostrils, lips, urinary meatus, vulva, anus gradually changes its structure to assume the histological characteristics of the internal mucosa. The functions of the skin are essential for the maintenance of life so that it can be considered a true and complex organ. Generally, it is more thick in some particular regions as back, palm, sole. Skin is elastic, and its smooth, soft and pliable surface is broken by intersetting lines, folds, ridges and pores.
Although you may not typically think of the skin as an organ, it is in fact made of tissues that work together as a single structure to perform unique and critical functions. The skin and its accessory structures make up the integumentary system , which provides the body with overall protection. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue Figure 5. The most superficial layer of the skin is the epidermis which is attached to the deeper dermis. Accessory structures, hair, glands, and nails, are found associated with the skin. The deeper layer of skin is well vascularized has numerous blood vessels and is superficial to the hypodermics.
