IMM250 PRACTICE EXAM QUESTIONS WITH ALL CORRECT ANSWERS Mechanisms through which neutrophils can kill microbes - Answer- - Antimicrobial peptides - Lysozyme - ROS (reactive oxygen species) - respiratory burst Reactive oxygen species - Answer- ROS are powerful oxidizing factors that kill pathogens - One way that phagocytes kill bacteria is by formation of NADPH oxidase from the combination of subunits(p67, p47, p40 and p22, gp91) which, with O2 forms ROS. Chronic Granulomatous Dise...

hypoxemia ~ low oxygen in the blood hypoxemic hypoxia ~ most common type of hypoxia, occurs when PaO2 drops below 80mmHg (such as due to altitude or disease impairing lung function) ischemic hypoxia ~ impaired tissue perfusion due to a cardiac or vascular disorder anemic hypoxia ~ oxygen carrying capacity of blood is reduced histoxic hypoxemia ~ tissues are unable to use the oxygen due to poisoning, such in the case of cyanide which prevents mitochondrial enzymes from synt...
