Test 3 riddlers
Show Answers:

  1. Zones of the spleen

  25. Enfamil
    based on human milk, undigested proteins and fats
  26. anemia of chronic disease
    • low serene iron and reduced iron binding capacity with abundant iron stores. Hepcidin is released by the liver in response to IL1 and TNF, this inhibits iron release

  34. cAMP
    turns on protein kinase A that phosphorilates the CFTR R domain
