What is the body

The human body is a complex biological system, called the body. In turn, it is composed of systems of bodies responsible for important life processes.

What is the body

The organism - a living body, characterized by special properties that distinguish it from non-living matter. As separate individuals, it is a structural unit of the population-species level of life and is considered one of the main objects of study in biology and anatomy. Organisms are divided into nuclear and non-nuclear. Depending on the number of cells divided by unicellular and multicellular. The basis of the formation of multicellular organisms is the process of differentiation of the cells, tissues, organs, with subsequent integration into the phylogeny and ontogeny. Many of them organized intra community (for example, a family in humans) .Organy and organ systems only work in interaction with each other. That's what creates the unity of the human body. All processes are carried out by means of the nervous system, which is involved in the dissemination of the necessary chemicals and provides humoral regulation. Such substances are hormones and are produced by the endocrine glands. They regulate the processes of growth, development and metabolism in the body. Nervous and humoral regulation complement each other, provide communication and coordination of all organs and sistem.Organizm can not exist without an environment. From this it receives food, water, salts, vitamins, oxygen and other components necessary for its normal functioning. An important feature of an organism is its adaptation to changing environmental conditions. The ability to save an organism constancy of its internal state called homeostasis. This is the result of close communication between all authorities and their systems. Homeostasis allows to regulate the amount of water and minerals in the body, its temperature and the level of blood glucose.
