which organ secretes most of the plasma proteins .heart .pancreas .brain .liver .kidney
Liver
Choose the correct statement regarding hemolytic disease of the newborn(HDN)
Unlike anti A and Anti B antibodies anti Rh antibodies are able to cross the placenta and enter the fetal bloodstream
Eileen is a strict vegan and therefore eats no animal products. She develops an anemia that her doctor thinks is caused by a nutritional deficiency. Which of the following is the likeliest candidate? .Lack of intrinsic factor .Vitamin K deficiency .Vitamine B12 deficiency .Vitamine B6 deficiency .Iron deficiency
Vitamin B12 deficiency
The disease sick cell anemia is an example of what can happen if .red blood cells bind too much oxygen .hemolysis is prevented by a bad gene .there is insufficient heme in the hemoglobin .a gene for adult hemoglobin is abnormal . the diet is deficient in iron
a gene for adult hemoglobin is abnormal
why can't a person with type A blood safely receive blood from a person with type B blood
a person with type A blood will have anti B antibodies that will agglutinate with type B blood
Bill wants to determine his blood type, so he takes a few drops of blood from a puncture wound in his finger and mixes it with various antisera. His blood cells agglutinate when mixed with the anti-A sera but not with the anti-B or anti-D sera. which of the following is true .bill is Rh negative .bill could receive type A negative blood in transfusion .bills plasma contains Rh antibodies .bills plasma contains B antibodies .bill could donate blood to an individual with type AB blood
bills plasma contains Rh antibodies
