Etiology (Ans- Cause of particular disease on microscopic level
Pathogenesis (Ans- Story of how disease develops
Atrophy (Ans- Decrease in the size of the cells, results in reduced tissue mass
Hypertrophy (Ans- Increase in cell size, results in enlarged tissue mass
Hyperplasia (Ans- Increased number of cells, results in enlarged tissue mass
Metaplasia
(Ans- Mature cell type is replaced by a different mature cell type, Ex:
chronic smokers, cells lose cilia
Dysplasia (Ans- Cells are different looking varying in size and shape

Neoplasia (Ans- New growth, commonly a tumor. May be malignant or benign
Apoptosis (Ans- Programmed cell death, normal occurrence in the body
Ischemia (Ans- Deficit of oxygen in the cells
Hypoxia (Ans- Reduced oxygen in the tissues
Iatrogenic
(Ans- illness or disease process because a medical process was done ex:
CAUTI
