what are the 7 functions of the integumentary system

Iontophoresis, also called electromotive drug administration, is a technique that uses a small electric charge to deliver a medicine or other chemical through the skin. helps protect the skin from abrasion. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. The integumentary system is comprised of your skin as well as your appendages. Ergo, the skin protects the body from fractures if we do not otherwise get enough of this vitamin from food-based sources. The integumentary system - the system that makes up our skin, nails, hair and certain glands - is not only the largest body system but has multiple functions to keep our bodies in homeostasis and running smoothly. Start studying The Integumentary System. 100. If our skin touches a cold object (like a cold drink), then we will lose heat via the process of conduction, which is the direct heat transfer of heat from a hotter surface, to a colder surface touching that hotter surface. Sweat gland: A sectional view of the skin (magnified), with the eccrine glands highlighted. The exact extent to which this process help keep us cool is debated (read below). 0 votes . This is because in a healthy individual, when all else is held equal, their body is constantly generating heat as a result of its various metabolic and physical processes. The skin assists in homeostasis (keeping different aspects of the body constant, e.g., temperature). Join now. Ask your question. At rest, such an individual is expected to increase their body temperature by 1 C every 5 minutes as a result of these processes. These flat hairs increase the flow of air next to the skin and increase heat loss by convection. Chapter 5: The Integumentary System What are the structures and functions of the integumentary system? Absorption. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature. Our online integumentary system trivia quizzes can be adapted to suit your requirements for taking some of the top integumentary system … Receptors are spread throughout the body, with large numbers found in the skin. Vitamin D further helps in the absorption of the calcium & maintenance of the phosphorus levels in the body. List four protective functions of the skin. The first way involves the abundance of blood vessels found in the dermis, the middle layer of the skin. •Body temperature regulation •If too hot • Dermal blood vessels dilate • Vessels carry more blood to surface so heat can escape •If too cold • Dermal blood vessels constrict • Prevents heat from escaping It protects our deeper tissues and organs from infections by fighting harmful bacteria & germs. Thus, this system is present all around the body as a protective cover against all kinds of damages. The integumentary system functions are varied but overall it provides a barrier that protects our body from infection. Name the two stages in the hair growth cycle. The skin has many functions, including serving as an enclosing barrier and providing environmental protection, regulating temperature, producing pigment and vitamin D, and sensory perception. It is about 2 meters squared (depending on the size of the individual). The integumentary system keeps body temperature within limits even when environmental temperature varies; this is called thermoregulation. Functions of the Integumentary System. Body Temp Regulation. One of the chief functions of the integumentary system is protection. Skin is more than just color, thickness, or texture. Protects the body from dehydration 4. In humans, the most important compounds in this group are vitamin D3 (also known as cholecalciferol) and vitamin D2 (ergocalciferol). Describe the ways in which the integumentary system protects the body. The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. It is located deep in the dermis, in the subcutaneous fat. PLAY. Human skin: This image details the parts of the integumentary system. This process is known as vasoconstriction. Describe the role of glands in excretion and absorption. Oftentimes these signs point to an underlying cause of disease in the body. This allows for our body to release a lot of body heat through radiation. The integumentary system distinguishes, separates, and protects the organism from its surroundings, but also plays a key metabolic function, as the major region for vitamin D production. Signs that the integumentary system isn’t healthy may be rashes, brittle nails and unhealthy hair. Gravity. Gross Anatomy of the Integumentary System. blood vessels constrict. This extraordinary organ system protects the internal structures of the body from damage, prevents dehydration, stores fat, and produces vitamins and hormones.It also helps maintain homeostasis within the body by assisting with the regulation of body temperature and water balance. The integument is the body’s largest organ and accounts for 15% of body weight. In this lesson, we'll explore the function of the different parts of the integumentary system, which protects the body. Additionally certain medications can be administered through the skin. Langerhans cells in the skin also contribute to protection as they are part of the adaptive immune system. blood vessels dialate. The Merkel receptor is a disk-shaped receptor located near the border between the epidermis and dermis. Owing to its location at the barrier of the environment and our internal selves, and its relatively very large surface area, it is plays an incredibly important role in thermoregulation. The integumentary system consists of the skin, hair, nails, glands, and nerves. The deepest layer is the hypodermis, which is primarily made up of adipose tissue. The stimulus for the secretion of apocrine sweat glands is adrenaline, which is a hormone carried in the blood.
