What is the function of the integrated system?

The main function of the integrated system is to provide a protective cover for the body. This system includes skin and related structures such as hair, sweat and oil glands and nails. It creates a barrier against hot and low temperatures, harmful chemicals and sunlight, as well as microorganisms. In addition, it has a major role in the sense of touch and helps to maintain the body temperature. Similarly, the integrated system is important for vitamin D production and plays a small role in waste excretion.

This system is the first defense of the body against damage or injury. The skin protects internal organs and other structures from friction caused, such as scratches or slices. It also maintains microorganisms such as bacteria. The hair insulates the body, protects it from sunlight, and, among other things, keep irritating substances outside the eyes. Nails prevent the ends of the fingers and legs. Evaporation of sweat from the skin requires heat, which helps to cool the body. It can be up to 2 gallons (7.5 liters) or more in extreme pof an appointment. When body temperature increases, blood flow also increases to the skin where excess heat is lost by convection. In colder environments, blood flow decreases to the skin, which reduces heat loss.

Provision of information about the organism environment is also the main function of the integrated system. The nerve ends in the skin allow the body to reduce temperature, pressure and touch changes. The top layer contains receptors responsible for a feeling of touch, while those in the lower layer of the skin can sensing heat and cold, pressure and pain. Hair follicles, but not hair itself, also respond to the touch.

Helping the body to create vitamin D is an important role of skin. Part of the process occurs when the ultraviolet light from the sun hits precursor molecules in the skin. Changed molecules are later converted into an active form of vitamin D in the kidneys and liver. The body can produce all the necessary vitamin D in this waythat there is enough sunlight.

The smaller function of the system is waste excretion. Pot is almost all water, but contains a small amount of waste products such as urea, uric acid and ammonia. Other organs such as kidneys play a much greater role in getting rid of the body of waste products.
