Skin is the largest organ of the integumentary system. Specifically, you will learn about: The functions of the organs of the integumentary system - the skin, hair, and nails - including protecting the body, helping to regulate homeostasis, and sensing and interacting with the external world. It also protects us a great deal from harm and allows us to sense our surrounding environment. IN humans the integumentary system includes the skin – a thickened keratinized epithelium made of multiple layers of cells that is largely impervious to water. The skin, in its own way, functions as a form of armor—body armor. Your email address will not be published. One of the metabolic functions of the skin is the production of vitamin D3 when ultraviolet light reacts with 7-dehydrocholesterol. Test.

Recognize the role of non-cellular components of skin in maintaining an integumentary system capable of healing. Finally, the … Pressure or tearing of tissue, keratin toughens cells; pressure receptors alert nervous system of damage. Diagnose tissue injury based on the depth of skin loss. The sympathetic nervous system is continuously monitoring body temperature and initiating appropriate motor responses. Match. Sebum secreted by the sebaceous glands helps create a skin surface that is hostile to many pathogens. The skin is made of multiple layers of cells and tissues, which are held to underlying structures by connective tissue (Figure 1). Gravity. Functions of the Integumantary System are.... Epidermis. The skin performs six primary functions which include, protection, absorption, excretion, secretion, regulation and sensation. Physiology (Function) of the Integumentary System The skin and accessory structures perform a variety of essential functions, such as protecting the body from invasion by microorganisms, chemicals, and other environmental factors; preventing dehydration; acting as a sensory organ; modulating body temperature and electrolyte balance; and synthesizing vitamin D. This system includes the skin and related structures, such as hair, sweat and oil glands, and the nails. Functions of the Integumentary System. Learn. Functions of the Integumentary system 1. protection a) chemical factors in the skin: Sebum (or oil) from the sebaceous glands is slightly acidic, retarding bacterial colonization on the skin surface. Discuss the primary functions of the integumentary system. Identify each layer of the skin and its components and discuss their functions. 2) Explain the 5 functions of the skin including how each relates to homeostasis. Match. The integumentary system, consisting of the skin, hair, nails, sebaceous (oil), and sweat glands, has a protective and regulatory function and, indirectly, an aesthetic one as well. Along with skin, several other glands and different sensory units like somatosensory receptors and nociceptors are also a part of this organ system. For any form of armor, a breach in the protective barrier poses a danger. It also contains specialized cells that secrete melanin to protect the body from the carcinogenic effects of UV rays and cells that have an immune function. Created by. Integumentary system function. integumentary system function 3. this system helps keep the body from drying out, provides a natural sunscreen, and acts as storage for fatty tissues necessary for energy, with the aid of sunshine it provides vitamin d, also provides sensory input and unpleasant sensations involving pressure and temperature . The integumentary system functions are varied but overall it provides a barrier that protects our body from infection. Thermoregulation is supported through the sweating and regulation of blood flow through the skin. Key Concepts: Terms in this set (19) Mechanical Damage. The skin performs a variety of functions: Protection is provided against biological invasion, physical damage, and ultraviolet radiation. provides the body with a CHEMICAL BARRIER via secretions that lower pH Required fields are marked *, Samsung Galaxy S21 Plus 5G review, advantages, disadvantages & features, Flexors of forearm, Forearm muscles, structure, function & anatomy, Samsung Galaxy S21 5G review, advantages, disadvantages & features, Uses of the concave mirror and the convex mirror in our daily life, Advantages and disadvantages of using robots in our life, Robot teachers uses, advantages and disadvantages, Copyright © Science online 2014. Chapter 5 Integumentary System Functions of the Integumentary System (I.S.) One function of the integumentary system is thermoregulation, the process that allows the body to maintain its core internal temperature. mfalat. It provides a barrier between your vital, life-sustaining organs and the influence of outside elements that could potentially damage them. Integumentary System: Skin Functions. Petite Protection Rhinos Regulation of Body Temperature Can’t Cutaneous Sensation Mimic Metabolic Function Big Blood Reservoir Elephants Excretion Protection The I.S. Skin is composed of two main layers, the epidermis and dermis. Its main function is to act as a barrier to protect the body from the outside world. The integumentary system is the largest of the body’s organ systems, made up of the skin and its associated appendages. Also present are important components of the immune system, collectively called the skin-associated lymphoid tissue. The integumentary system protects against many threats such as infection, desiccation, abrasion, chemical assault, and radiation damage. #bhushanscience#integumentarysystem#skinfunctionIn this video we discussed about the Functions of Skin. Acc … Learn. Gravity. Key Concepts: Terms in this set (52) - Maintains body temperature - Protection - Largest Sense organ - Excretion - Synthesis of Vitamin D - Immunity - Functions of skin derivatives. Signs that the integumentary system isn’t healthy may be rashes, brittle nails and unhealthy hair. Each of these layers performs important roles in keeping our body healthy. 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. Spell. For any form of armor, a breach in the protective barrier poses a danger. Sweat from the sudoriferous glands is slightly hypertonic and can flush off most bacteria on the skin surface.
