The integumentary system
The integumentary system is the organ system that protects the body from damage , comprising the skin and its appendages (including hair and nails).The integumentary system has a variety of functions; it may serve to waterproof , cushion , and protect the deeper tissues , excrete wastes , and regulate temperature , and is the attachment site for sensory receptors to detect pain , sensation , pressure , and temperature.
Layers of the skin.The integumentary system is the largest of the body`s organ systems.In humans , this system accounts for about 12 to 15 percent of total body weight and covers 1.5-2m2 of surface area.It distinguishes , separates , and protects the organism from its surroundings.
The human skin (integument) is composed of a minimum of 3 major layers of tissue: the epidermis; dermis; and hypodermis.The epidermis forms the outermost layer , providing the initial barrier to the external environment.Beneath this , the dermis comprises two sections , the papillary and reticular layers , and contains connective tissues , vessels , glands , follicles , hair roots , sensory nerve endings , and muscular tissue.The deepest layer is the hypodermis , which is primarily made up of adipose tissue.Substantial collagen bundles anchor the dermis to the hypodermis in a way that permits most areas of the skin to move freely over the deeper tissue layers.
The integumentary system has multiple roles in homeostasis.All body systems work in an interconnected manner to maintain the internal conditions essential to the function of the body.The skin has an important job of protecting the body and acts as the body`s first line of defense against infection , temperature change , and other challenges to homeostasis.Functions include:
Protect the body`s internal living tissues and organs.
Protect against invasion by infectious organisms.
Protect the body from dehydration.
Protect the body against abrupt changes in temperature , maintain homeostasis.
Help excrete waste materials through perspiration.
Act as a receptor for touch , pressure , pain , heart , and cold.
Protect the body against sunburns by secreting melanin.
Generate vitamin D through exposure to ultraviolet light.
Store water , fat , glucose , and vitamin D.
Maintenance of the body form.

Aid in physical examination as color of the skin may indicate many conditions e.g. it becomes yellowish in jaundice.

early detection of the first signs of the disease. We pay much attention to the popularization of medical science among the population. We believe that one the main available methods of preventing the spread of diseases is health education. The press, cinema, radio and television are very helpful for this purpose.
The basic medical unit in our country is the polyclinic. We have policlinics for the adult population and for children. Ambulant patients are seen at the policlinic by the district doctors. A patient who is ill at home is visited by his district doctor. The doctor works 6 hours a day. For the district doctor this is made up of 3 hours in consultation at the policlinic and 3 hours in visiting patients in their homes.
The emergency ambulance service operates day and night and is free of charge. The ambulances are equipped by diagnostic, respiratory, anesthetic and electro-therapeutic apparatus, blood-transfusion and other equipment.
There are several specialized hospitals in Russia for the treatment of particular diseases – infections, psychiatric diseases, cancer, ophthalmological diseases and others.
Some words must be said about the Mother-and-Child Health Care Centre in Moscow. This centre concentrates effort not only on traditional problems of obstetrics and gynecology but also on research in normal physiology of the female organism. The main task of this centre is to ensure the birth of a healthy child. The centre developed new methods of disease prevention, diagnostics and treatment. Much attention in our country is paid to the scientific problems, concerning the prevention and treatment of cardiovascular, viral and oncological diseases, the problems of gerontology, medical genetics, immunology and the creation of artifical organs.
