What is the meaning of the term cellular adaptation? Cells are able to adapt to workload or threats to survival by changing their size, number, and form What are the types of adverse changes? 1. Disuse 2. Overuse or increased workload 3. Hormonal Response (increase or decrease) 4. Environmental Stress (smoke, chemicals, etc.) 5. Environmental Stress (smoke, chemicals,etc.) 6. Chronic Irritation (smoke, viruses, etc.) What are the different types of cellular adaptation? 1. Atropy 2. Hyp...

Anemia Definition Reduction in the total number of erythrocytes (RBCs) in the circulating blood OR Decrease in quantity OR quality of Hb This results in ↓O2 carrying capacity of the blood Hypoxemia Hypoxia Causes Impaired erythrocyte production Blood loss (acute/chronic) Increased erythrocyte destruction Mild S/S Fatigue/Weakness/Dizzy Pallor (skin and mucus membranes) Cold hands and feet Nail changes (become brittle) Hair loss Dangerous S/S SOB/Dyspnea Chest pain/Arrhythm...

Acute Short term; Fast on set Chronic Long term; Slow on set Compensatory Mechanism Physiological response to homeostatic imbalance (Positive or negative feedback mechanism) Congenital Born with Etiology Cause of disease Homeostasis Body natural balance Iatrogenic Unintended affect of treatment

The study of the disorder or breakdown of the human body's function? Pathophysiology. Disease usually occurs when? A disruption in homeostasis or deviation. -Dynamic process -The relative consistency of the body's internal processes -Give and take system -Equilibrium is necessary for all cellsSelf-regulating -Compensatory -Negative feedback-most common; Ex-temp regulation -Positive feedback-Ex: blood clot -May use many means to correct one imbalance Homeostasis Age Gender Genetic...

Acute New, usually of rapid onset and of concern, opposite of chronic Asymptomatic showing no symptoms of disease Chronic Long-standing, constant. Opposite of acute Clinical manifestations the presenting signs and symptoms of the disease Complications New secondary or additional problems Concept a general idea that can be applied to similar situations Diagnosis the process of discovering exactly what is wrong with someone or something, by examining them closely Disease the functional im...

What is the difference between pathophysiology and pathology? Pathophysiology: the study of the functional bodily changes that occur as a result of an injury, disorder, or disease (the mechanisms of disease) Pathology: the study of changes in cells and tissues as a result of injury or disease (studying a disease) What is a syndrome? a specific condition with a recognizable, predictable pattern Define pathogenesis. the disease beginning; when the disease process begins until symptom on...

Pathophysiology the study of the functional changes that occur in the body as a result of an injury, disorder or disease Pathology study of changes in cells and tissues as a result of injury or disease Pathogenesis the disease beginning Disease the functional impairment of cells, tissues, organs Etiology cause of disease Primary prevention prohibits a disease condition from occurring Secondary prevention it's the early detection of disease through screening and early treatment Tertia...

Pathophysiology the study of diseases (pathology) and the study of the functions of the body (physiology) Pharmacology study of drugs Etiology the study of causes/reasons. Identifies causal factors. Causal Factors what causes the disease or virus to infect. Idiopathic cause is unknown Iatrogenic of or relating to illness caused by medical examination or treatment. eg. Iatrogenic disease, Iatrogenic pneumothorax Risk Factors factors that put you at higher risk for certain illnesses or di...
