Adaptation
In-biological concept it represents morpho-functional reconstraction of organism/organ which directed to providing of his existence at the condition of uninjured deviation from the biological constants of environment and internal environment.

Compensation (indemnification)
General biological concept, which represents concrete, more narrow display of morpho-functional changes which directed to the correction of the broken functions in a sick organism through its individual situational reactions

Hypertrophy
Hypertrophy (from a lat. hyper - superfluously, trophe is feed) is volume multiplying the of cell, tissue or organ due to reproduction of cells or multiplying an amount and sizes of intracells ultrastructures.

Hyperplasia
Hypertrophy is inalienably( невід’ємно) related to hyperplasia (from a lat. plaseo - I form) which shows up in reproduction of cells the way of mitosis (cellular hyperplasia), excrescence of tissues (tissue hyperplasia) and ultrastructures (intracellular hyperplasia).

Atrophy
Atrophy is occurring during one’s lifetime diminishing of organs volume, tissues and cells, which is accompanied to weakening or stoppings of their function.

Regeneration
By a term regeneration (from a lat. regeneratio is renewal) marked the process of renew of the organized matter in the area of damage. Self-renew takes place at molecular, subcellular, cellular, tissue and organ levels and removes principle of autoadjusting (autoregulate) of vital functions.

Organization Organization is the protective –
adaptation process, directed to separation & substituting of the necrosis, hemorrhage or exsudate, and also blood clots, foreign bodies and vermin niduses (hearths) by granulation tissue

Fibrin organization (lung carnification).The type of organization is encapsulation around the trichinella
