The integumentary system is a very vital piece of an intricate puzzle commonly known as the human body. It may seem like a very small piece, but it does so much. It helps protect tissues and organs, regulate body temperature, synthesize and store energy, detect certain senses, and excrete wastes. Within itself, this system has a multitude of components including multiple layers of skin, hair follicles, nails, and various glands. Individually, and as a whole unit, these components serve a highly important purpose. One crucial function of the integumentary system is protection. It is made up of multiple layers of skin, including the epidermis and dermis, which cover the entire body. This helps to shield the underlying tissues and organs. It protects these precious parts from chemicals, infections, impact damage, and sun exposure. Along with this protection, it helps to prevent major loss of important internal bodily fluids. Temperature maintenance is another function provided by the integumentary system. It helps the body maintain homeostasis by adjusting accordingly to keep it at a steady, normal body temperature. The environment is the biggest enemy when it comes to body temperature regulation. When it is cold outside our body has to try to adjust by heating up, we usually aid this process by putting on multiple layers of clothing so heat can be entrapped and absorbed by the skin. When it is hot outside our body temperature rises, causing it to produce sweat. This sweat moves from the sweat gland duct in the dermis up to the epidermis, in hopes to help lower internal temperatures. In addition, the integumentary system also helps synthesize and store nutrients/energy/food. When exposed to sunlight, or artificial sunlight, the epidermis is triggered to synthesize vitamin D. This is crucial because it in turn helps a hormone which results in calcium buildup within the body. Also, the dermis helps hold in vast amounts of lipids, which includes various fats, oils, and waxes. Sensory reception is also provided by the integumentary system and is a very essential part of our everyday lives. It helps us detect pressure, pain, temperature, and foreign stimuli. All of these things are then passed along to the nervous system. Touch and pressure receptors are located in the dermis and hypodermis. The hair shafts and follicles are a main part of this reception process. They help by detecting and warning us of foreign objects coming in contact with the body. They also become stiff and stand up straight when we are exposed to cold temperatures triggering temperature maintenance. They even keep certain foreign particles from entering our bodies via eyes and nostrils. The final function of the integumentary system is that of excretion and secretion. Various glands throughout the dermis and epidermis help release liquids such as sweat and water, salts, and organic wastes. Sweat must be released to maintain proper body temperature and also helps dilute chemicals that could be harmful when in contact with the skin. This function also aids in the secretion of breast milk, as the mammary glands are similar to those of apocrine sweat glands. The layers of skin in the integumentary system also help to quickly respond to injuries and attempt to ensure they do not become serious injuries. For example, calluses form on hands and feet when more external pressure is placed on them in attempt to protect the underlying tissues with this thicker layer of skin. But when a more serious injury occurs such as a scrape, cut, or incision occurs, the skin
Acne-Acne is a skin disease marked by pimples on the face, chest, and back. The most common skin disease. Increased levels of androgens cause the sebaceous glands to secrete an excessive amount of sebum into hair follicles. The excess sebum combines with dead, sticky skin cells to form a hard plug that blocks the follicle. Bacteria that normally lives on the skin then invades the blocked follicle. Weakened, the follicle bursts open, releasing the sebum, bacteria…
The Integumentary System
The Three Main Layers of Skin:
1. Epidermis: The first layer of skin is called the Epidermis. It is composed of stratified squamous epithelium that is keratinized. It contains the keratinocytes and melanocytes, it is avascular, and is the tissue layer above skin. It is the BARRIER Layer. The Epidermis is made up of five different layers:
Stratum Corneum: known as the “horny” layer, dead, stratified squamous, and it looks rough. This layer can become thick (callus) from…

The Integumentary System
By: Sasha Caldwell
The Integumentary System has multiple important roles in maintaining
life. It includes protection, temperature regulation, sensory reception, biochemical synthesis, and absorption. All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the human body. The Integumentary System contains the largest organ in the human body, the skin. The skin cushions and protects the delicate organs beneath…
The integumentary system consists of the skin, hair, nails, and glands. The word INTEGUMENT comes from a Latin word that means “covering”. The skin is the largest organ of the body that is waterproof and airtight so that water and other things keep out. With the skin being waterproof it helps the body to stay dry and prevents the body from losing its fluids and drying out. The skin protects the body from many infectious organisms and harmful effects of ultraviolet radiation. The skin also helps control…
physiology refer to the structure and function of cells respectively. Whether you are looking at the human body, a plant, or a part of one of those organisms, how it is built is the anatomy and how it works is the physiology. The purpose of this essay is to analyze the normal anatomy and physiology of human skin then look at how the skin is altered in the disease state, Acne Vulgaris. We will explore the symptoms of, and treatment for, acne. Lastly, we will explore studies performed on nonwesternized…
Chapter 5: Integumentary System -Burns and the Rule of Nines
A burn is a tissue damage caused by excessive heat, electricity, radioactivity, or corrosive chemicals that denature the proteins in the skin cells. Burns are graded according to their severity. A first-degree burn involves only the epidermis (sunburn). A second-degree burn destroys the epidermis and part of the dermis (blister). A third-degree burn is a full-thickness burn that destroys the epidermis, dermis, and subcutaneous…

for medical and physical care (Julia, 1998). It has been argued that so much emphasizes were done on treatment of diseases that very little notice was left for the psychological, social, cultural and economic differences between individuals. This essay will describe and explain how different theories can be applied in real nursing practice.
The well-being of a person greatly depended holistically were nursing theories started to evolve and emerge. Holistic nursing is a practice of nursing…
