Blood has four major components: (1) a fluid component called plasma,
e e e e e e e e e e




(2) circulating solutes such as ions, (3) serum proteins, and (4) cells. Plas

rombin, and plasminogen. The hematopoietic cells comprise the remainin

ANS: C e




Erythrocytes (RBCs) are flexible biconcave disks without nuclei whose pri
e e e e e e e e e




mary component is an oxygen-
e e e e




carrying molecule called hemoglobin. RBCs are generated from precursor
e e e e e e e e e




stem cells under the influence of a growth factor called erythropoietin. Eryt
e e e e e e e e e e e




hropoietin is secreted by the kidney in response to a perceived decrease in
e e e e e e e e e e e e e




perfusion or tissue hypoxia. Reticulocytes are immature RBCs that may be
e e e e e e e e e e e




released when there is a demand for RBCs that exceeds the number of avai
e e e e e e e e e e e e e




lable mature cells. The oxygen affinity for hemoglobin is modulated primaril
e e e e e e e e e e




y by the concentration of 2,3-diphosphoglycerate (2,3-
e e e e e e




DPG) and depends on the blood pH and body temperature.
