Chapter 13 Blood Flashcards
blood composition
cells (45% of blood volume)
plasma (55% of blood volume)
Cells
erythrocytes (RBC)
leukocytes (WBC)
platelets or thrombocytes (clotting cells)
plasma
liquid portion of blood
- a solution of water, proteins, sugar, salts, hormones, lipids, and vitamins
drop of blood
4-6 million RBCs
7-10 thousand WBC
150-450 thousand platelets
hematopoietic stem cells
cell in the bone marrow that gives rise to all types of blood cells
differentiated
change in structure and function of a cell as it matures
hemoglobin
enables the erythrocyte to carry oxygen
- blood protein containing iron
erythrocytes
RBC originate in the bone marrow
erythropoietin
simulates the production of erythrocytes
- hormone secreted by kidneys
macrophages
migrates from blood to tissue spaces
and destroys the worn out erythrocytes
- located in the spleen, liver, and bone marrow
heme releases
iron and decomposes into yellow-orange pigment called bilirubin
granulocytes
polymorphonuclear leukocytes
WBC with cytoplasmic granules
- eosinophil
- basophil
- neutrophil
eosinophil
granules that stain with red acidic dye (eosin)
Basophils
granules that stain a dark blue with a basic (alkaline) dye.
Neutrophils
phagocytes
granulocytic leukocyte formed in bone marrow
- accumulate at infection sites where they ingest and destroy bacteria
colony stimulating factors (CSFs)
protein factor that stimulates growth and differentiation of developing blood cells
Granulocyte-CSF
GranulocyteMacrophage-CSF
given to cancer patients to restore granulocyte production
erythropoietin
can be produced by recombinant DNA techniques
polymorphonuclear
mulitlobed nuclei
polymorphonuclear granulocytes
aka neutrophils
mononuclear
pertaining to a cell with a single round nucleus
lymphocytes
made in the bone marrow and lymph nodes and in the bloodstream and in the lymphatic system
lymphocytes
protects body against infection
antibodies
specific protein (immunoglobulin) produced by lymphocyte in response to bacteria, viruses, or antigens.
- antibody is specific to antigen and inactivates it
monocytes
leukocyte with one large nucleus
= phagocytic cells that fights disease
macrophages
move from the bloodstream into tissues and dispose of dead and dying cells
megakaryocytes
large platelet precursor cell found in the bone marrow
4 major plasma proteins
- albumin
- globulins
- fibrinogen
-prothrombin
albumin
maintains the proper proportion and concentration of water in the blood
edema
results when too much fluid in the blood leaks into the tissue
globulins
plasma proteins
- alpha
- beta
- gamma
immunoglobulins
aka gamma globulins
protein with antibody cativity
IgG
found in high concentration in plasma
IgA
found in breast milk, saliva, tears, and respiratory plasma
plasmapheresis
the process of separating plasma from cells
packed red cells
whole blood with most of the plasma removed
hemolysis
breakdown of red blood cells
disseminated intravascular coagulation (DIC)
excessive clotting in blood vessels
