Trophy is the totality of cellular nutrition processes that ensure the vital functions of cells of tissues and organs. Trofika represents the unity of the processes of assimilation and dissimilation, synthesis and decay.
Distinguish the following trophic states. Eutrophy is the right diet, in which there is no abnormality in the structure, function and growth of tissues. Hypertrophy (see) - increased nutrition, which leads to an increase in the size of organs and tissues, either by increasing the size of cells (actually hypertrophy), or increasing their number (hyperplasia). Hypotrophy - reduced nutrition, resulting in a decrease in size (hypotrophy) or number (hypoplasia) of cells or both. Atrophy (see) - a complete lack of nutrition, leading to the disappearance of cells of this group. Dystrophy (see Dystrophy of cells and tissues) is an abnormal diet that causes pathological changes in the structure of tissues.
In the regulation of trophism, an important role belongs to specific trophic nerves and glands of internal secretion.
