blood system Flashcards
plasma
liquid part of blood that includes clotting factors
serum
liquid part of blood without clotting factors (when mixed with clotting factors it becomes plasma)
erythrocytes
red blood cells transport oxygen
leukocytes
white blood cells fight infects
thrombocytes
clot blood
hematopoiesis
produces blood
idiopathic thrombocytopenic purpura
autoimmune disease with antibodies against several platelet surface antigens
hemophilia
excessive bleeding caused by lack of plasma clotting factors
hypercoagulation
excessive coagulation caused by overly activated coagulation cascade
type a
a antigen, b antibody
type b
b antigen, a antibody
type ab
a and b antigen, no antibodies
type o
no antigen, both a and b antibodies (universal donor)
anemia
lack of iron intake
aplastic anemia
failure of blood cell production due to deficiency of hemotopoietic stem cells in bone marrow
sickle cell
hereditary disorder that caused abnormal shape of erythrocytes and results in hemolytic anemia, jaudice and splenomegaly
pernicious anemia
lack of mature erythrocytes due to inability to absorb vitamin b12 (large shape)
thalassemia
inherited autosomal recessive blood disorder involved with the inability to produce enough hemoglobin
hemochomatosis
inherited autosomal blood disorder that causes excess iron deposits in body
hereditary spherocytosis
imparing membrane proteins that normally allow for the erythrocytes to stay in biconcave shape
anisocytosis
increased variation in size of red cells
poikilocytosis
varied in shapes in erythocytes
polycythemia vera
increase in all varieties of blood cell numbers
granulocytosis
abnormal increase in granulocytes in the blood
granulocytopenia
a deficiency or abnormal decrease in number of granulocytes
mononucleosis
infectious disease marked by increased number of lymphocytes
leukemia
increase number in cancerous white blood cells
multiple myeloma
malignant neoplasm of bone marrow
apheresis
separation of blood into a few components and removal of a select part from the blood
autologous blood transfusion
collection of blood from a single patient and re-transfusion back to the same patient with required
bone marrow biopsy
microscopic examination of bone marrow removed with needle
