WGU pathophysiology D236-Exam Questions and Answers 2022/2023 What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? - ANSWER Starling's Law describes how fluids move across the capillary membrane. There are two major opposing forces that act to balance each other, hydrostatic pressure (pushing water out of the capillaries) and osmotic pressure (including oncontic pressure, which pushes fluid into the capillaries). Bot...

2 main groups of the digestive system - alimentary canal and accessory digestive organs 3 parts of the colon - ascending, transverse, descending absorption - movement of nutrients into the bloodstream accessory digestive organs - teeth, tongue, salivary glands, liver, gallbladder, pancreas afferent goes (into/ out of) capsule - into alimentary canal - (gastrointestinal/ GI tract) digestive tube that extends from the mouth to the anus alimentary canal organs - mouth, pharynx, esophagus, st...

peyers patches - large collections of lymphoid tissue found in the submucosa of the small intestine function of peyers patches - prevent the pathogens to gain access into the body from digestive system during absorption of food follicles collect and phagocytose the bacteria which enters through digestive system from food ILF - isolated lymphoid follicle found in mucosa of GI tract monitor and respond to antigens in the gut to initiate immune systems composed of B and T cells, dendrit...

Explain the challenges of diagnosing autoimmune disorders. Your Answer: This is challangeing because it can affect the cells of the tissues of body system and blood . There are over 80 identifiable, many are overlapping and non specific. you need to follow PT, physical evendence and serological finding to get the correct autoimmune diagonosis. There are over 80 identified, many with overlapping presentations. Many manifestations are nonspecific and are seen in other non-autoimmune diseas...

MICR 270 TESTED QUESTIONS WITH ANSWERS REVISED & UPDATED!! Steps of innate TLR recognition - Answer-1) TLRs recognize PAMPs/DAMPs and initiate phagocytosis 2) Phagocyte presents pathogen on its cell surface through a complex called peptide:MHC complex (phagocyte is now an antigen-presenting cell) 3) Phagocyte stimulates production of costimulatory molecules, which increase strength of antigen-presenting process 4) T-cell binds to the peptide:MHC complex, which activates the T-cell Inflamm...

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...
