P. decrease in mitochondrial function, decreased production of ATP increases anaerobic metabolism.
eventual cell death.
C.M. hypoxia, cyanosis, cognitive impairment, lethargy
Free radical and ROS - (ANSWER)E. normal byproduct of ATP production, will overwhelm the
mitochondria- exhaust intracellular antioxidants
P. lipid peroxidation, damage proteins, fragment DNA
C.M. development in Alzheimer's, heart disease, Parkinson's disease, Amyotrophic Lateral Sclerosis
Ethanol - (ANSWER)E. mood altering drug, long term effects on liver and nutritional status
P. metabolized by liver, generates free radicals
C.M. CNS depression, nutrient deficiencies-Mag, Vit B6, thiamine, PO4, inflammation and fatty
infiltration of liver, hepatomegaly, leads to liver failure irreversible
Oncosis - (ANSWER)Na and H2O enter cell and cause swelling. Organ increases in weight, becomes
distended and pale. Associated with high fever, hypocalcemia, certain infections
Fatty Infiltration - (ANSWER)intracellular accumulation of lipids in the liver
liver fails to metabolize lipids. usually from ETOH or high fat diet. can lead to cirrhosis
dystrophic calcification - (ANSWER)accumulation of Ca in dead or dying tissues
calcium salt clump and harden- interfere with cellular structure and function
r/t pulmonary TB, atherosclerosis, injured heart valves, chronic pancreatitis
metastatic calcification - (ANSWER)accumulation of Ca in normal tissue
result of hypercalcemia r/t hyperparathyroidism, hyperthyroidism, toxic levels of Vit D. Can also r/t
hyperphosphatemia in renal failure
