    Anatomy of the Integumentary System

  • Epidermis. The epidermis is the most superficial layer of the skin that covers almost the entire body surface.
  • Dermis. The dermis is the deep layer of the skin found under the epidermis.
  • Hypodermis.
  • Hair.
  • Nails.
  • Sudoriferous Glands.
  • Sebaceous Glands.
  • Ceruminous Glands.
  • What is the structure of integumentary system?

    The integumentary system is an organ system consisting of the skin, hair, nails, and exocrine glands. The skin is only a few millimeters thick yet is by far the largest organ in the body. The average person’s skin weighs 10 pounds and has a surface area of almost 20 square feet.

    What are the structures and functions of the integumentary system?

    The integumentary system consists of the skin, hair, nails, glands, and nerves. Its main function is to act as a barrier to protect the body from the outside world. It also functions to retain body fluids, protect against disease, eliminate waste products, and regulate body temperature.

    What is the function of the subcutaneous layer of the skin?

    The subcutaneous tissue layer also functions to protect the muscles and bones whenever we fall or hit our bodies on something. The last function of the subcutaneous tissue layer is to act as a passageway for the blood vessels and nerves from the dermis of the skin into the muscles.

    What are the major functions of the skin?

    The most important functions of the skin are: Regulates body temperature. Prevents loss of essential body fluids, and penetration of toxic substances. Protection of the body from harmful effects of the sun and radiation.

    How does the integumentary system and the skeletal system work together?

    Bones are grown to protect our major organs and to help us move. What other systems do the Integumentary and Skeletal system work with? The Integumentary system works with the muscular system to protect the muscles. They produce heat,and increases blood flow to the skin.

    What are the three layers of the skin?

    Skin has three layers:

  • The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.
  • The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.
  • The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
  • What percentage of your body weight is made of skin?

    Your skin is your largest organ. It covers your entire body and has a surface area of around 2 square metres. Its thickness varies from 0.5mm on your eyelids to 4mm or more on the palms of your hands and the soles of your feet. In total, it accounts for around 16 percent of your body weight.

    What is the main function of the hair?

    Hairs (or pili; pilus in the singular) are characteristic of mammals. The functions of hair include protection, regulation of body temperature, and facilitation of evaporation of perspiration; hairs also act as sense organs. Hairs develop in the fetus as epidermal downgrowths that invade the underlying dermis.

    How does the integumentary system work to regulate body temperature?

    The integumentary system has multiple roles in homeostasis, including 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 body.

    What is the function of the endocrine system?

    The endocrine system is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs. These hormones regulate the body’s growth, metabolism (the physical and chemical processes of the body), and sexual development and function.

    What is the function of the immune system?

    The immune system is the body’s defense against infectious organisms and other invaders. Through a series of steps called the immune response, the immune system attacks organisms and substances that invade body systems and cause disease.

    What are the major structures and functions of the skeletal system?

    The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. The skeletal system performs vital functions — support, movement, protection, blood cell production, calcium storage and endocrine regulation — that enable us to survive.

    How does the nervous system work with the integumentary system?

    The skeletal system also protects internal organs and produces blood cells. Bones provide calcium that is essential for the proper functioning of the nervous system. The vertebrae protect the spinal cord from injury. Sensory receptors in joints between bones send signals about body position to the brain.

    What is the epidermis for?

    Epidermis: The upper or outer layer of the two main layers of cells that make up the skin. The epidermis is mostly made up of flat, scale-like cells called squamous cells. Under the squamous cells are round cells called basal cells. The deepest part of the epidermis also contains melanocytes.

    What does the skin?

    Skin is an elastic covering. It protects you against exposure to dangerous things in the environment such as bacteria. It also repels water, minimises water loss from the body and protects underlying structures such as blood vessels, nerves and organs.

    What is the role of the skin in the immune system?

    The skin acts as a barrier, a kind of sheath, made of several layers of cells and their related glands. The skin is a dynamic organ that contains different cells which contains elements of the innate and the adaptive immune system which are activated when the tissue is under attack by invading pathogens.

    How do you keep the integumentary system healthy?

    Error loading player:

  • Bathe every day and wash your hands regularly.
  • Apply sunscreen before you spend time outdoors.
  • Eat a healthy well-balanced diet.
  • Examine your entire body on a regular basis.
  • Avoid wearing things that are too tight on your body.
  • Don’t smoke cigarettes.
  • How does the skin function in the regulation of body temperature?

    The skin’s immense blood supply helps regulate temperature: dilated vessels allow for heat loss, while constricted vessels retain heat. The skin regulates body temperature with its blood supply. Humidity affects thermoregulation by limiting sweat evaporation and thus heat loss.

    What is the exocrine glands?

    Exocrine glands are glands that produce and secrete substances onto an epithelial surface by way of a duct. Examples of exocrine glands include sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.

    What is the largest organ in the body?
