Cellular Adaption Flashcards
Atrophy
Reduction in cell size
Reduces 02 consumption
Hypertrophy
Increased cell size and functioning tissue mass
Hyperplasia
Increase in number of cells in an organ or tissue
Metaplasia
Reversible change in one adult type is replaced by another cell type
“Change in the tissue”
Dysplasia
Deranged cell growth of a specific tissue
Maybe reversed if irritant removed
Dystrophic calcification
Deposits of calcium salts in injured tissue
Metastatic calcification
Depósitos of calcium salts in injured tissue
Metastatic calcification
Deposition of calcium salts because of elevated serum levels of calcium
Free radical injury
Highly reactive chemical
Hypoxia
Cell deprived of O2
Ischemia
Impaired O2 delivery to the tissues, organs, body
What is calcium’s purpose?
Messenger and signs for cell responses
Hypoxemia
Deficiency of O2 in the blood
Infarction
Area of dead tissue in an organ caused by blockage of blood supply to the area
Necrosis
Death of small area of tissue or organ
