Med term- chapter 8- blood and lymphatic system

hematopoiesis

*formation* of RBCs

reticulocyte

*immature* RBC

Leukocytosis

*increase* in number of *WBCs*

elliptocyte

*oval* RBCs

Hemoglobin -

*protein* in the RBCs that *carries oxygen* to the cells -iron containing pigment in RBC

immunoglobulin

*protein* that provides *protection* (immunity) against dz

lymphatic system

-Collects fluid (edema) from the body tissues -lympho

Three types of cells found in the blood:

-Erythrocytes (red blood cells) -Leukocytes (white blood cells) -Thrombocytes (platelets)

Conditions of clotting

-Hemophilia -Hemorrhage -Ecchymosis -Petechia

function of lymphatic system

-Immunity - lymphocytes -Cleaning of fluid in lymph nodes -Replenish blood volume

Disorders of the hematological system

-Low erythrocytes - pale and tired -Low platelets - bruising -Low leukocytes - infection

Disorders of the lymphatic system

-Swollen lymph nodes -Swelling in extremities

Too many cells would be a

-cytosis

lymphocytes = WBCs

-produced in the lymph nodes, spleen, and bone marrow. -They circulate throughout the body in the blood and lymphatic fluid.

Condition of red blood cells

Anemia - reduced erythrocytes, symptoms of fatigue

Ig

Immunoglobulin

Proteins dissolved in the blood

Immunoglobulins

erythrocyte

RBC

spherocyte

RBC that assumes spherical shape

lymphedema

Swelling in the arms and/or legs

leukocyte

WBC

erythrocytosis

abnormal *increase* in the *number of RBCs*

asplenia

absence of a spleen or of a spleen function

lymphadenopathy

any dz of a lymph gland (node) -used to refer to noticeably swollen lymph nodes, especially in the neck

Immunoglobulins

any of a *class of proteins* present in the serum and cells of the immune system, that function as *antibodies*

Immunoglobulins play an essential role in the body's immune system. They

attach to foreign substances, such as bacteria, and assist in destroying them.

embolism

blockage in a blood vessel caused by an embolus

Embolism -

blockage of blood vessel by an embolus

hemo/hemato

blood

Thrombus -

blood clot

-emia

blood condition

Hemophilia -

blood does not clot

myelo

bone marrow

splenolysis

breakdown (destruction) of spleen tissue

hemolysis

breakdown of blood cells

Thrombogenic -

capable of creating a clot

cyto

cell

thrombocyte

cell that helps the blood clot

thromb/o

clot

Thromboembolism -

clot that traveled to another place

coagul/o

coagulation (the blood gels).

microcytosis

condition characterized by *small RBCs*

anisocytosis

condition characterized by a great inequality in the *size of RBCs*

elliptocytosis

condition characterized by increase in the number of oval shaped RBCs

hemophilia

condition in which the blood doesn't clot, thus causing excessive bleeding

poikilocytosis

condition of characterized by RBCs in a variety of shapes

Thrombosis -

condition of having a *clot*

-penia

deficiency

pancytopenia

deficiency in *cellular components* of the blood

leukopenia

deficiency in WBCs

lymphopenia

deficiency in lymph

Olgiocthemia

deficiency in the number of RBCs

neutropenia

deficiency of a *neutrophil*

splenectopy

displacement of the spleen -floating spleen

splenoptosis

downward displacement (drooping) of the spleen

hepatosplenomegaly

enlargement of the liver and spleen

pale and tired= low?

erythrocytes

polycythemia

excess of RBCs

Hemorrhage -

excessive blood loss

hemorrhage

excessive blood loss

myelopoiesis

formation of bone marrow

Anisocytosis -

great inequality in size of RBCs

immuno

immune system

hypoperfusion

inadequate flow of blood

Polycythemia -

increased number of all blood cells

reperfusion injury

injury to tissue that occurs after blood flow is restored

Macrocytosis -

large RBCs micro= small

Ecchymosis -

large bruise

Thrombocytosis -

large number of platelets

infection= low?

leukocytes

lymphocyte

lymph cell

Collected fluid flows into

lymphatic vessels

Hodgkin's disease is a type of

lymphoma in which antibody-producing cells of the lymphatic system begin to grow abnormally.

hematoma

mass of blood within an organ, cavity or tissue

Embolus -

mass of matter in blood

Asplenia -

no spleen

Normocyte -

normal sized RBC

normocyte

normal sized RBC

thymic hyperplasia

overdevelopment of the thymus

thrombocyte, aka?

platelet

Thrombocytes

platelets

bruising = low?

platelets

phagocytosis

process in which phagocytes (WBC) destroy (eat) a foreign MO or cell debris

Pancytopenia -

reduction in the number of blood cells

Petechia -

small bruise

splenomalacia

softening of the spleen

spleno

spleen

splenalgia

spleen pain -splenodynia

hematology

study of blood

antibody

substance *produced by the body* in *response to an antigen*

Antigen

substance that will *cause the production* of an *antibody*.

lymphedema

swelling caused by abnormal accumulation of lymph -usually in extremities

hematocrit

test to judge or separate the blood -judge *ratio of RBCs to total blood volume*

thymo

thymus

tonsillo

tonsils

Oligocythemia -

too few erythrocytes

Thrombocytopenia -

too few platelets

Erythrocytosis -

too many erythrocytes

phlebo/veno

vein

lymphatic empties into

veins
