PATHO 370 Week 5 Midterm Exam 2023 COMPLETE. Rheumatic heart disease is most often a consequence of β-hemolytic streptococcal infection. 25.How do clinical conditions that increase vascular permeability cause edema? By allowing plasma proteins to leak into the interstitial fluid, which draws in excess fluid by increasing the interstitial fluid osmotic pressure 26.In contrast to all other types of shock, the hyperdynamic phase of septic shock is associated with high cardiac output 27.Aft...

Why do we need immunological tolerance? ~~> This allows us to get random generation of the repertoire of BCR and TCR This means self-reactive specificities will be made Without tolerance, we will get self destruction How do lymphocytes become tolerant? ~~> Central tolerance - they encounter antigens in the central lymphoid organs when they are immature Peripheral tolerance - they encounter antigens in the peripheral tissues in the absence of other necessary signals What is t...

(slide 1:2) a. true b. false - a. true A vaccine is attempting to stimulate the adaptive immune system to create a better innate response. (slide 1:2) a. true b. false - b. false *A vaccine is attempting to stimulate the adaptive immune system to create MEMORY. However, we are just beginning to appreciate the role of the innate immune system in this process. In order to ...

What is the specific/adaptive immunity? ~~> induced by exposure to an infection, very specific and has memory Describe the receptors in the specific immune response ~~> clonaly distributed, a large repitoire at a low frequency What is clonal selection? ~~> during development, cells recognising self material are destroyed leaving only those recognising non-self Whats the role of clonal selection? ~~> reduces the repertoire leaving a pool of mature naive lymphocytes which ca...

Chapter 9: Immunogenetics 1. Which of the following best describes immunogenetics? A) The study of genes involved in immune responses B) The study of infectious diseases C) The study of cancer genetics D) The study of hereditary disorders Answer: A Rationale: Immunogenetics focuses on the genetic factors that influence the immune system's response to pathogens and diseases. NCLEX preference: Understanding immunogenetics is crucial for assessing patient responses to infections and va...
