Which statement is true concerning hemoglobin A Hgb transports O2 and CO2 B Hgb is on Red Blood Cells C Hgb is on White Blood Cells D Anemia can decrease available Hgb?
Hemoglobin is on RBCs, not WBCs. Hemoglobin picks up CO2 from
cells and takes it to the lungs, where it releases CO2 and picks up
O2. Anemia can reduce available Hgb in the bloodstream. So can any
illness, condition, or disease which affects RBC production.
