What is a way that Adaptive Immunity can recruit innate immunity? ------CORRECT ANSWER-------The innate immune response to microbes stimulates adaptive immune responses and influences the nature of the adaptive responses. Conversely, adaptive immune responses often work by enhancing the protective mechanisms of innate immunity, making them more capable of effectively combating pathogenic microbes Why are some infections harder on children while other infections are harder on the elderly? ...

MICR 271 TESTED QUESTIONS WITH REVISED ANSWERS – UPDATED!!! How do complements work? - Answer-circulate in blood, inactive, if activated: increased inflammation of local cells enhanced phagocytosis or formation of channel forming complex called membrane attack complex (causes lysis of pathogen), effective against gram negative bacteria (it can pierce outer membrane Distinguish between the different methods natural killer cells use to destroy their cell targets - Answer-kill cells by sec...

WGU D236 PATHOPHYSIOLOGY FINAL EXAM 2 VERSIONS WITH 100% CORRECT QUESTIONS AND ANSWERS VERSION 1 Explain Starling's Law of Capillary Forces and how it causes edema. - Starling's hypothesis states that the fluid movement due to filtration across the wall of a capillary is dependent on the balance between the hydrostatic pressure gradient and the pressure gradient across the capillary. This causes edema by the retention of water in the tissues instead of vascular system. Why is it...

BIOL 2200: PATHOPHYSIOLOGY CASE STUDY 1 QUESTIONS AND ANSWERS 100% PASS Why is there blood in his urine? Due to swelling/inflammation of testes, the plasma fluid must be released to relieve pressure which is done via the vas deferens then to the urethra Why is there shortness of breath? He's in emotional stress due to the severe scrotal pain Why is there severe scrotal pain? The kinin system activates proteins that assist with inflammatory response. A major kinin is bradykinin wh...

HUMAN IMMUNODEFICIENCY VIRUS INFECTION QUESTIONS AND CORRECT ANSWERS GRADED A++ HIV can be transmitted as a result of contact with infected blood, semen, vaginal secretions, or breast milk. Transmission of HIV occurs through (3) sexual intercourse with an infected partner exposure to HIV-infected blood or blood products perinatal transmission during pregnancy, at delivery, or through breastfeeding Variables that influence whether infection will be established after an exposure include ...

Phases of Inflammation: Vascular Permeability - Inflammation stimulates blood vessel dilation and opening of capillary pores. Capillary pores allows fluid and cells (WBCs and platelets) to arrive at site of injury. Phases of Inflammation: Cellular Chemotaxis - Chemical signal that calls out to WBC's to site of injury. Results in leukocytosis, where WBCs are released from the bone marrow and into the blood stream. **Doctor is able to analyze the type of WBC and number of WBCs to determine ...
