Question | Answer |
Functions of the Blood System | - to transport oxgygen, carbon dioxide, nutrients, electrolytes, vitamins, hormones, and wastes throughout the body - To protect the body with circulating white blood cells, antibodies of the immune system, and clotting factors |
All cells come from | stem cells |
An immature RBC | Reticulocyte. Becomes mature when enters bloodstream |
Structure of Blood System | Blood is connective tissue -45% formed element -55% liiquid/plasma |
Formed elements are comprised of | produced in the bone marrow - erythrocytes - carry oxygen - leukocytes - provide immunity - thrombocytes - key role in hemostasis (clotting) |
Blood plasma consists of | -90% water -10% components transported throughout the body |
Blood | fluid that circulates throughout the heart, arteries, capillaries, and veins, transporting oxygen and nutritive materials to the tissues |
Blood : formed elements | blood cells |
Blood : plasma | liquid portion of blood that carries formed elements, clotting factors, minerals, and proteins |
Blood : serum | liquid portion of blood after removal of clotting factors and blood cells |
Bone marrow (blood forming organ) | soft tissue within bone, with multiple functions including the production of blood cells |
Bone marrow : erythropoietin (EPO) | hormone released by kidneys that stimulates red blood cell production in bone marrow |
Bone marrow : hematopoiesis | formation of blood cells and other formed elements |
Spleen (blood forming organ) | vascular lymphatic organ responsible for filtering blood, destroying old red blood cells, producing red blood cells before birth , and storing blood |
Formed element : erythrocyte | blood cell that carries oxygen and carbon dioxide |
Erythrocyte : Hemoglobin (HGB , Hb , Hgb) | protein in red blood cells that binds to oxygen; gives red blood cells the characteristic color |
Iron (Fe) | essential trace element necessary for hemoglobin to transport oxygen on red blood cells |
Erythrocyte : Macrocyte | a large red blood cell |
Erythrocyte : Rh factor | protein substance present in the red blood cells of most people (85%) that is capable of inducing intense antigenic reactions |
Formed element : leukocyte | white blood cell , largest blood cell , protects against pathogens, foreign substances, and cell debris |
Leukocyte : granulocyte | white blood cell with visible granules; the three types of granulocytes are named according to the type of dye each is attracted to |
Leukocyte : agranulocyte | white blood cell without clearly visible granules |
Different types of leukocytes | -Granulocytes : neutrophil , eosinophil , basophil -Agranulocytes : lymphocyte , monocyte |
Formed element : thrombocyte , platelet (PLT) | cell fragments in the blood that stick together, forming a clot |
Blood Clotting : Clotting Factors | any of the various plasma components involved in the clotting process |
Blood Clotting : Coagulation | clotting; changing from liquid to a solid state |
Blood Clotting : Fibrin | elastic fiber protein needed in clotting and produced by fibrinogen |
Blood Clotting : Fibrinogen | plasma protein that is converted into solid threads called fibrin |
chrom/o , chromat/o | color |
cyt/o | cell |
erythr/o | red |
granul/o | granules |
hem/o , hemat/o | blood |
immun/o | immune, safe |
leuk/o | white |

neutr/o | neutral |
nucle/o | nucleus |
path/o | disease |
phag/o | eat, swallow |
phleb/o | vein |
plas/o | formation , growth |
thromb/o | blood clot |
auto- | self, same |
basi- , baso- | base |
macro- | large, long |
micro- | small |
mono- | one |
pro- | before, promoting |
poly- | many, much |
-cyte | cell |
-emia | blood (condition of) |
-sis | condition, process |
-gen | origin, production |
-lysis | destruction , breakdown , separation |
-osis | abnormal condition |
-penia | deficiency |
-philia | attraction for |

-rrhage | flowing forth |
-y | condition of |
hematopoietic | pertaining to the formation of blood cells |
hemolytic | pertaining to the rupture or destruction of red blood cells |
hemorrhagic | pertaining to profuse or excessive bleeding |
