Adaptation-compensational processes According prof. Ya.Ya.Bodnar Assistant-prof. V.Voloshyn
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.
Hypertrophy Veritable Unveritable Phisiological At pathological conditions Hyperplasia Compensational Vicaric (substitute) Cell Neuro-humor Intracell Hypertrophy excrescence Tissue
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.
Disfunctional At blood supplying insufficient From pressure Tropho-neurotic From phisical & chemical acts ATROPHY At pathological conditions Phisiological Common Local Alimantary emaciation (kahexy) Cancer depletion (kahexy) Cerebralkahexy Hypophyseal depletion Kahexyat chronic infections
Local atrophy • a – dysfunctional • b – insufficient of blood supplying • c – tropho-neurotic • d – from pressure
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.
Regeneration Physiologic Reparatic Pathologic Restitution Hyporegeneration Substitution Hyperregeneration Regenerativ hyperthrophy Cellular hyperplasia Intracellular hyperplasia
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
Wounds healing (cicatrization) Epitelisation Under scab By primary strain By secondary strain
Metaplasia • Direct or mediated converting of one type of tissue into other
