Basic Concepts of Pathophysiology

Physiology the study of functions and processes that occur in the body Pathophysiology the study of the underlying changes in body physiology that result from disease or injury Homeostasis maintenance of constant conditions in the body’s internal environment stressors challenges to the body’s balance Compensation the return to homeostasis after Read more…

Pathophysiology and Pharmacology Unit 1

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…

Pathophysiology

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…

Physiology Is the study of specific characteristics and functions of a living organism and its part. T/F Pathophysiology is the study of abnormalities in physiologic functions of living beings. True. T/F Pathophysiology is the physiology of altered health. True. T/F Pathophysiology is the structural and functional changes in cells, tissues, Read more…

Pathophysiology Cellular Function

pathophysiology the study of the disorder or breakdown of the human body function health may be considered the absence of disease disease occurs when there is a disruption in homeostasis or deviation from normal homeostasis a dynamic process that establishes equilibrium. it is self-regulating, compensatory. trying to establish a balance Read more…

Patho Ch. 01: Intro to Pathophysiology

Primary prevention: Actions aimed at prevention of disease. Seat belt, chlorination and fluoridation of water, sunscreen, helmet, nutritious diet, taking vitamins, washing of hands. Secondary prevention: Actions (mainly, screening) aimed at early detection and prompt treatment of disease. Pap smear, mammogram, physical Tertiary prevention: Treatment and rehabilitation measures aimed at Read more…

Pathophysiology- Cancer

What is neoplasia? Disorder of altered cell differentiation and growth (new growth) Growth is uncoordinated and relatively autonomous autonomous Lacks normal regulatory controls over cell growth and division, tends to increase in size and grow after stimulus ceases or needs of organism are met Nomenclature for BENIGN tumors Named according Read more…

Pathophysiology I

Pathophysiology The study of abnormal states, specifically the functional changes that accompany a particular syndrome or disease. Disease An interruption, cessation, or disorder of the body system or organ structure that is characterized usually by a recognized etiologic agent or agents an identifiable group of signs and symptoms, or consistent Read more…

Immunity: Pathophysiology

How are the defenses of immunity divided? The defenses of immunity are divided into: 1. 1st line of defense 2. 2nd line of defense 3. 3rd line of defense First Line of Defense Innate resistance Second Line of Defense Inflammation Third Line of Defense Adaptive (acquired immunity) -normal immune response Read more…

Nursing pathophysiology

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 and Pharmacology Exam 1

Pathophysiology the study of underlying changes in body physiology that result from disease or injury. Etiology study of the cause of disease Clinical manifestations s/s, evidence of disease, local and systemic Risk factors predisposing) increase disease probability, but do not cause. Complications onset of disease while having an existing disease Read more…

Foundations of Pathophysiology

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…

pathophysiology – Terms to know

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…

pathophysiology: disorders and diseases

AIDS a syndrome caused by the human immunodeficiency virus (HIV) that renders immune cells ineffective, permitting opportunistic infections, malignancies, and neurologic diseases to develop; transmitted sexually or through contaminated blood HIV What enveloped RNA retrovirus infects CD4 T cells and uses the enzyme reverse transcriptase? HIV protease Enzyme coded for Read more…

Pathophysiology Definition

Pathophysiology The study of the underlying changes in the body physiology that result from disease or injury Incidence the number of new cases occurring in a specific time period Prevalence the number of existing cases within a population during a specific time period Endemic regularly found among particular people or Read more…

Pathophysiology: Key Terms
