CH6 Flashcards
Plasma
the pale yellow liquid component of blood; includes every aspect of blood except for the
formed elements
Enucleated
a cell that does not contain a nucleus
erythrocytes
red blood cells (RBCs); the most common type of blood cell; transports oxygen and
carbon dioxide; get their red color from the hemoglobin content
erythropoiesis
the production/formation of red blood cells
hematopoiesis/hemopoiesis
the production/formation of all blood cells, which takes place in the
bone marrow
hemoglobin
the iron-containing protein in red blood cells that carries oxygen; causesRBCs to have a red color
red bone marrow
produces blood cells
agranulocytes
cells that do not have granules within the cytoplasm (lymphocyte and monocyte)
granulocytes
cells with granules in their cytoplasm (basophil, eosinophil and neutrophil)
leukocytes
white blood cells (WBCs); cells of the immune system that protect the body against
foreign invaders and infectious disease
pathogens
disease generating organisms such a bacteria, viruses and fungi
phagocyte
a cell that has the ability to ingest and digest bacteria and foreign particles
agglutinate
to clump together; thrombocytes clump together into small clusters when a blood
vessel is cut or damage
clotting factors
any of a number of substances in blood plasma that are involved in the clotting
process
coagulate
to convert from a liquid to a gel or solid, as in blood coagulation
hemostasis
the stopping of a flow of blood; literally means blood standing still
thrombocytes/platelets
clotting cells; stop bleeding by clumping and clotting at the site of blood
vessel injury
* not actual cells, but are fragments of a megakaryocyte
anemia
a large group of conditions characterized by a reduction in the number of red blood cells
or a reduction in the amount of hemoglobin in the blood
aplastic anemia
a severe form of anemia that develops as a consequence of loss of functioning red
bone marrow; results in a decrease in the number of all the formed elements
dyscrasia
a general term indicating the presence of a disorder/disease affecting blood
embolus
a clot (blood, fat or air) that breaks loose from the original site and floats in the blood,
possibly occluding or stopping blood flow elsewhere
erythrocytosis
condition of too many red blood cells
erythropenia/erythrocytopenia
condition of too few red blood cells
hematologist
one who specializing in the study of blood diseases and conditions
