their blood lacks A or B antibodies
People with type AB blood are considered the "universal recipient" for transfusions because
55;92
Plasma composes about ________ percent of whole blood and water composes ________ percent of the plasma volume.
interstitial fluid
Plasma is closest in composition to
Immunoglobulins
Plasma proteins essential in body defense are the
megakaryocytes
Platelets are pinched off from giant multinucleated cells in the bone marrow called
erythropoietin
Red blood cell production is regulated by the hormone
4 months
The average life span of a red blood cell is
proteins
The chief difference between plasma and interstitial fluid involves the concentration of
agglutination
The clumping of red blood cells, when the specific antibody against the antigen on the cells is added, is called
whole blood
The combination of plasma and formed elements is called
thrombin
The conversion of fibrinogen to fibrin is catalyzed by the enzyme
vascular spasm
The first step of hemostasis is
water
The most abundant component of plasma is
albumins
The most abundant proteins in blood plasma are
neutrophils
The most numerous white blood cells in peripheral circulation are the
hematocrit
The percent fraction of formed elements relative to whole blood is the
Erythropoiesis
The process of red blood cell production is called
RBCs have both the A & B surface antigens and no ABO plasma antibodies

liver
Which organ secretes most of the plasma proteins?
eosinophils
White blood cells that are increased in allergic individuals are the
basophils
White blood cells that release histamine at the site of an injury are
presence of specific glycoproteins on the cell membrane

45
A typical adult hematocrit is
red bone marrow
All the circulating red blood cells in an adult originate in the
serum
Blood that has clotting proteins removed is termed
neutrophils
During a bacterial infection you would expect to see increased numbers of
iron
Each heme ring in hemoglobin encloses an atom of
the liver
Most of the protein factors that are required for clotting are synthesized by
