Pathology ch 1

What is the study of diseases? Pathology
Disease is the bodies response to some form of? Injury(may be hereditary, traumatic, infectious, vascular, or metabolic)
The disease will prevent itself by a set of characteristics known as signs and symptoms. The determination of diseases is called what? Diagnosis
What is the prediction of the outcome of the disease? Prognosis
What is the study of causation of a pathologic process called? Etiology
Acute______ is the initial response of body tissues to local injury. (Regardless whether the injury is penetrating trauma infectious organisms or chemical substances where there are four events that occur sequentially.) Inflammation
What's the sequence in which acute inflammation occurs? 1. Alternations in blood flow & vascular permeability 2. White blood cells migrate to the area of injury 3. The process of digestion of dead cells & tissue occurs 4. Repair
The increase in blood flow to injury site is called? Hyperemia
The venules and capillaries become_____ Permeable.
The allowance of passage of protein rich plasma across vessel walls is Permeable
What is the process of digestion of dead cells and tissue occurs called? Phagocytosis
The ____ microorganism produces ______. Pyogenic ; pus
What are two examples of pyogenic microorganisms? Staphylococcus & streptococcus
An ____ is localized and usually is encapsulated ___ of _____. Abscess ; collection of pus
This is a tumor like mass of tissue caused by a chronic inflammatory process. Granuloma
Give an example of granule a Tuberculosis
This is a bacteria in the blood and which can then invade other organs and tissues of the body is called? Bacteremia
This is an abnormal amount of fluid in tissue spaces or body cavities. Edema
Generalized _____(______) becomes systemic and can produce swelling in tissues throughout the body. Edema or anasarca
This is the lack of blood supply to an organ or part of an organ. The organs cells and tissues are deprived of oxygen and nutrients. Ischemia
This sometimes reroutes the blood supply. Collateral vessels
Slowly developing conclusions are less likely to cause tissue death. Cells of the___&____ undergo irreversible damage if deprived of their blood supply for how long? Nervous system and myocardial muscle cells. 3 to 5 minutes
This is the localized area of ischemia necrosis within a tissue or organ. Infarct
What is the infarct produced by Occlusion a of either its arterial supply or its venous damage
What would be caused by a blood clot? Thrombotic occlusion
What are caused by blood clots, plaque, masses of bacteria or cancer cells? Embolus conclusions
What is twisting of the bowels called? Volvulus
This is the rupture of a blood vessel. Hemorrhage
This is the reduction in the size or number of cells in an organ or tissue, with a corresponding decrease in function. Atrophy
This refers to an increase in size of the cells of a tissue or organ in response to demand for increased function Hypertrophy
This is an increase in the number of cells in a tissue or organ. Hyperplasia
This is the abnormal development of tissue. Dysphasia
This is any new and abnormal growth especially when the growth is uncontrolled and progressive. Neoplasia
Give an example of neoplasia Tumor cells may flourish because normal cells and tissues are competing for their metabolic needs
This is the malignant neoplasms invade and destroy adjacent structures and spread to distant sites Metastasize
Most benign rumors closely resemble what? The tissue of origin
Give some types of benign tissues. Fibromas, chondromas, Adenoma, cystadenomas, lipomas, angiomas, polyp
Malignant neoplasms of epithelial cell origin are called Carcinomas
What do carcinomas affect? Epithelial tissues, skin, and mucous membranes lining body cavities
This refers to malignancies of glandular tissues Adenocarcinoma
Give examples of adenocarcinoma Breasts, liver, and pancreas, and of cells lining the gastrointestinal tract
Sometimes the tumor grows without form and is called Undifferentiated or anaplastic
These are highly malignant rumors arising from connective tissues such as bone, muscle, and cartilage. Sarcomas
These are less common than carcinomas but tend to spread more rapidly Sarcomas
The major metastatic route of carcinomas, especially those of the lungs and breasts are spread how? Lymphatic
What determines the most appropriate therapy for tumors? Staging
These are disease that pass from one generation to the next through the genetic information contained in the nucleus of each cell? Hereditary diseases
Hereditary diseases may or may not show at birth? They do not occur at birth
What types of diseases are present at birth? Congenital
This is characterized by impairment of cellular immunity that results in recurrent opportunistic infections. AIDS acquired immunodeficiency syndrome
AIDS is caused by infections with what and is known as what? RNA(retroviruses); HIV(human immunodeficiency)
What is the most prevalent inflammatory disease of the liver? Hepatitis
What is the most common cause of hepatitis and what are the types? Viral infections or reaction to drugs and toxins; A, B, C, and E
How is Hepatitis B contracted and who is the most common to get it? Contracted through blood or blood products or through sexual contact; Healthcare workers are the most susceptible to the virus
