carbon tetrachloride cellular injuryLiver (centrilobular necrosis, fatty change)37.*Lead (cellular injury)- causes chemical injury- interferes with the functions of calcium & affects include the nervous system, the hematopoietic system (tissues that produce blood cells), & the kidneys- alterations in calcium may interfere w/ NTS which may cause hyperactive behavior & proliferation of capillaries of the white matter & intercerebral arteries- can occur in adults who work w/ metal, environmental exposure, pottery38.carbon monoxide cellular injury- has a higher affinity for hemoglobin (300x) so it quickly binds w/ the hemoglobin, preventing oxygen molecules from doing so39.*Ethanol (cellular injury)- acute alcoholism mainly affects the CNS but may induce reversiblehepatic & gastric changes40.Mercury (cell injury)...41.blunt force injuries examplescontusion, hematoma, abrasion, laceration, fractures42.blunt force injuriesApplication of mechanical energy to the body resulting in the tearing, shearing, or crushing of tissues43.contusionbruise, bleeding into the skin or underlying tissues44.hematomacollection of blood in soft tissue45.abrasionScrape of the skin due to something abrasive46.lacerationtear or rip resulting when tensile strength of skin or tissue is exceeded47.fractureblunt-force blows or impacts can cause bone to break or shatter48.sharp injuriesincised wounds, stab wounds, puncture wounds, chopping wounds49.incised wounda cut that is longer than it is deep50.stab wounddeeper than it is long
