Nails provide a protective covering on the dorsal surface of the distal part of a finger or toe. They can be useful when you need to pick up small objects or scratch an itch. Glands are also included in the integumentary system. There are two different types, sweat glands and oil glands. Sweat glands are distributed over the entire skin surface except the nipples and parts of the external genitalia, there are up to 3 million sweat glands on everyone.
Muscle tissue contract to produce active movement. Neural tissues conduct electrical impulses and carries information. The protected regions of our body for example our kidney tubes, the lining of the ventral body cavities and the lining of blood vessels are called simple squamous epithelium, they protect regions in which absorption takes place or where a slippery surface reduces friction. Stratified squamous epithelium protects when there are severe mechanical stresses the lining of the mouth and esophagus are prime examples of the epithelium. I believe that if the cutaneous membrane was damaged it would heal in time after all it is our skin and we know that in most people it heals with the help of red blood cells.
The integumentary system is the largest organ in the body. The integumentary system is composed of the skin and the structures related to the skin, which include the hair, the finger nails, the sensory receptors and the glands. This system has an important function since it provides protection to the body, helps to maintain body temperature, and contains sensory receptors. The skin being the largest organ makes up approximately 15 percent of the body’s total weight.1 The skin has two layers called epidermis and the dermis. The epidermis is the skins most superficial layer and it is composed of stratified squamous epithelial tissue.2 The epidermis is divided into four or five general layer called the strata.
Homeostasis is the property of a system in which variables are controlled so that internal conditions remain steady and relatively constant. Examples of homeostasis contain the regulation of body temperature and the balance between alkalinity and acidity (pH). It is a process that maintains the stability of the human body's internal environment in response to changes in external conditions. (American, 2000) Homeostasis is essentially an internal biological process in which the body maintains internal equilibrium. The variable that is being monitored in homeostasis process is known as the variable or controlled variable.
FUNCTIONS The integumentary system is essential to the body's homeostasis, or ability to maintain the internal balance of its functions regardless of outside conditions. The system works to protect underlying tissues and organs from infections and injury. It also prevents the loss of body fluids. Receiving about one-third of the blood pumped from the heart every minute, the skin and its glands help maintain normal body temperature. The system also acts as a mini-excretory system, secreting salts, water, and wastes in the form of sweat.
Another significant group of cell in the epidermis are melanocytes, the cells producing melanin, the pigment responsible for skin tone and color. Finally, Langerhans cells are essentially a forepost of the immune system in the epidermis. They prevent unwanted foreign substances from penetrating the skin. The condition of epidermis determines how "fresh" your skin looks and also how well your skin absorbs and holds moisture. Wrinkles, however, are formed in lower layers.
DERMATOLOGY Skin is the largest organ of the body, covering and protecting the entire surface of the body. The total surface area of skin is around 3000 sq inches or roughly around 19,355 sq cm depending on age, height, and body size. The skin, along with its derivatives, nails, hair, sweat glands, and sebaceous glands forms the integumentary system. Besides providing protection to the body the skin has a host of other functions to be performed like regulating body temperature, immune protection, sensations of touch, heat, cold, and pain through the sensory nerve endings, communicating with external openings of numerous other body systems like digestive system, urogenital system, and respiratory system via mucous membranes and also one of the most important function of acting as a storage house of energy by collection of adipose tissue, which is the principal fat depot in the body. It is the first line of defense of our body against any organism.
A conclusion will then be drawn based on the discussion. The brain is an essential organ of the body. It is the control center for all the body’s activities, such as walking, talking, swallowing, breathing taste, smell and heart beat. The brain also controls our thinking functions, our intellectual activities as well as our emotions. Hemispheric specialization refers to the dominance of one hemisphere of the brain in specific functions, such as language, emotions, motor control and so on ( Feldman, 2009).
Work effectively in the community sector Summative assessment 2 Project 1 Home and Community Care-New employee general information Ethics – are beliefs or principles set to define the “right” way to conduct yourself in a given situation. Any code of ethics will include certain individual rights such as the right to make our own choices, the right to justice the right to freedom of movement, the right to protection, the right to adequate shelter and the right to education these basic human rights are of high importance when dealing with our clients and must be adhered to at all times. The Victorian Charter of Human Rights and Responsibilities is an important document and underpins the way we interact with people at all times. Role- our role is to provide support and assistance to those wishing to remain living independently and safely in their own homes. We can do this by providing assistance with house cleaning, showering and dressing, minor home repairs, meal delivery and respite.
Sensory nerves send messages to the glands and the muscles, telling them what to do. Epithelial Tissue The functions of epithelial tissue include transportation of materials, protection of underlying tissues, absorption of water and nutrients and secretion of waste products. Epithelial tissue covers the whole surface of the body. It is made up of cells closely packed and ranged in one or more layers. This tissue is specialised to form the covering or
