I own a ask more or less hemoglobglin and erthrocytes...?

Hemogloblin circulating freely in the blood as a result of destabilized erythrocytes is removed by which action and how?
A. T cell
B. B cells
C. hemoglobinemia
D. haptoglobin


Answers:    D. haptoglobin

From http://en.wikipedia.org/wiki/Haptoglobin

"Haptoglobin is a protein within the blood plasma that binds free hemoglobin released from erythrocytes. The haptoglobin-hemoglobin complex will then be removed by the reticuloendothelial system (mostly the spleen). In clinical settings, the haptoglobin assay is used to blind for and monitor hemolytic anemia* "

A. and B. are incorrect:

From http://en.wikipedia.org/wiki/Reticulo-en...

"The reticuloendothelial system (RES) . . consists of the phagocytic cells located surrounded by reticular connective tissue, primarily monocytes and macrophages" (not T or B cells)

C. is wrong. It is merely the state of hemoglobin being contained by the plasma where it doesn't belong

From http://www.answers.com/topic/hemoglobine...

hemoglobinemia - The presence of hemoglobin contained by the blood plasma

*hemolytic anemia is anemia caused by the breaking of red cell which releases their hemoglobin content into the plasma
hemoglobin has two parts heme and globin.heme is the iron factor and globin is the protein part.The iron is used again for the synthesis of hemoglobin and the porphyrin ring open and forms bilirubin and it is oxidized to form biliverdin and excreted via faeces.
