Function of the immune system : 1) to protect the body from invasion by foreign antigens - foreign substances that trigger the immune response 2) to identify and destroy potentially harmful cells 3) to remove cellular debris What accomplishes the functions of the immune system? : lymphoid organs & specifically designed lymphocytes through the process of antibody-mediated immune response & cell-mediated immune response. General types of immune alterations - immune system acts inappropr...

The process of taking in and using food for growth, repair, and maintenance of the body includes ingestion, digestion, absorption, and metabolism : nutrition Inflammation : adaptive response of the body to injury or illness How many functions is the liver responsible for? : about 500 lobule : functional unit of the liver 2 hepatocyte : liver cells that produce and secrete bile bile : stimulates peristalsis and breaks down fats in intestine canaliculus : channels between hepatocy...

Immunity : Function of immune system is to protect body from invasion by foreign antigens to identify and destroy potentially harmful cells. Exaggerated immune response : -Against environmental antigens, allergy -Too much of an IR Misdirected IR against host's own cell : Autoimmunity Isoimmunity : Directed against beneficial foreign tissues Body's IS reacts against tissues of usually the same species -Transplanted tissue -Blood transfusion Immune deficiency : Deficient immune re...

Neoplasm : "new growth" tumor neoplasm Does not obey laws : of normal cell growth neoplasm continue to grow : at the expense of the host cancer cells exhibit "autonomy" : independence from normal cellular controls Cancer cells are also "anaplasia" : loss of differentiation or specialization 2 Benign : are NOT called "cancer" - tissue of orgin + "oma" ex benign tumor of fat cells = LIPOMA Malignant : cancer Mal=bad are usually named cell differentiation : the normal pr...

Oxygenation : The body's ability to deliver oxygen to all cells via the processes of ventilation, diffusion, and perfusion Diffusion : movement of oxygen across alveolar walls into pulmonary capillaries Ventilation : movement of atmospheric air into the alveoli Perfusion : movement of oxygen to and into the cells How does air come into the lungs? : Create more negative pressure in the pleural space (cavity) so it is less than atmospheric pressure. 2 Pleural space is ____ : A pot...
