What is Pathophysiology? a science that provides understanding of disease mechanism and how/why physiology changes in body structure and function lead to clinical manifestations of disease. pathology study of disease physiology study of functions of living organism Prevention: Primary health promotion and protection to reduce/prevent incidence of disease ei: immunization, Read more…
Hyperplasia Increase in cell number. Cells retain normal structure. Causes of hyperplasia – hormone signaling (uterine lining) – increased functional workload (increased blood cells due to high altitude living) Hypertrophy Increase in cell size. Cells retain normal structure. Causes of Hypertrophy – hormonal signaling (breast cells for lactation) – increased Read more…

Hypertrophy -increased size and functional capacity of cells -increased workload causes increase in size -will revert to normal if the cause is removed -ex: body buider–muscle mass Atrophy -decreased size and functional capacity -decrease use causes decreased size of cells examples: occurs in muscles, brain, and kidneys physiologic-uterus shrinkage post Read more…
Pathophysiology the study of underlying changes in body physiology that result from disease or injury.

Complications onset of disease while having an existing disease Read more…
Pathology the study of the structural (physical) changes in cells, tissues, and organs, due to disease or injury Pathophysiology the study of the physiological (functional) changes in cells, tissues, and organs, due to disease or injury Pathologist – diagnoses disease based upon structural and/or functional changes to aid in treatment, Read more…
Pathology A branch of medicine that deals with the structural and functional changes in tissues and organs of the body that cause or are caused by disease. Pathophysiology A specific branch of pathology that studies functional or physiologic changes in the body that results from disease processes. Anaerobic Metabolism and Read more…
etiology the study of the cause of disease (i.e. infections, heredity, alterations in immunity, malignancy, malnutrition, degeneration, or trauma) idiopathic cause of disease is unknown iatrogenic diseases that occur as a result of medical treatment example of iatrogenic antibiotic treatment that injures the kidney and results in renal failure is Read more…
