Define Acquired timing of etiologic agents? - Answer disease is caused by events AFTER BIRTH. (ex: result of genetic predisposition combined with exposure to a different etiologic agent-asthma(genetic and exposure to certain mites)
Define pathogenesis? - Answer the sequence of cellular or tissue events that take place in time from the initial contact with the etiologic agent until the ultimate expressions of a disease or the development
of the disease. IT IS THE PATTERN OF PROGRESSION. EX: Atherosclerosis(coronary artery disease)
Define morphology? - Answer refers to fundamental structure(how something looks) of cells tissues or organs.
