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...

Alteration due to Renal Failure/Disorders Hematocrit : Decreased - Anemia Due to decreased synthesis of erythropoietin. Erythropoietin stimulates bone marrow to produce RBC. When nephrons fail, kidneys cannot produce erythropoietin. Hematocrit - the ratio of the volume of RBCs to the total volume of blood; NOT caused by Anemia - IS Anemia Alteration due to Renal Failure/Disorders Potassium : Increased - Hyperkalemia Because Nephrons cannot excrete excess Potassium. Nephron damage or ...
