Chapter-8 The Blood and Lymphatic Systems- Hematology and Immunology Flashcards
coagul/o
roots
Def: coagulation
Ex: anticoagulant, coagulopathy
thromb/o
roots
Def: clot
Ex: thrombocyte, thrombosis
hem/o
roots
Def: blood
Ex: hemolysis
Note: the average-sized has almost 6 quarts of blood in his body. The average-sized woman has almost 4 quarts.
hemat/o
roots
Def: blood
Ex: hematology
cyt/o
roots
Def: cell
Ex: erythrocyte, thrombocytosis
leuk/o
roots
Def: white
Ex: leukocytes, leukemia
Notes: Leukocytes, which are white blood cells, act as the bloodstream’s police force and garbage collectors. They are the primary responders to infection and tissue damage. They also remove debris from the bloodstream through a process called phagocytosis (remember: phago means “to eat”) and begin the process of cell repair.
phleb/o
roots
Def: vein
Ex: phlebotomy
Notes: The term phlebotomy comes from phlebo (vein) and tomy (incision). It is the term used for drawing blood. But make sure you pronounce the word carefully: You don’t want to get some blood drawn (phlebotomy) and end up having a portion of your brain removed (lobotomy).
ven/o
roots
Def: vein
Ex: venospasm
lymph/o
roots
Def: lymph
Ex: lymphadenitis, lymphoma
Notes: Lymph comes from a Latin word meaning “water” or “spring” and refers to a clear liquid that circulates in the body, providing nutrients to cells and removing waste from them.
myel/o
roots
Def: bone marrow, spine
Ex: myelitis, myelodysplasia
-emia
suffix
Def: blood condition
Ex: anemia, leukemia
tonsill/o
root
Def: tonsils
Ex: tonsillitis, tonsillectomy
splen/o
roots
Def: spleen
Ex: splenomegaly, splenectomy
Notes: The spleen is an organ in the upper-left portion of your abdomen. One of its jobs is to filter old red blood cells out of your blood. A human can live without a spleen with no adverse effects, which is good news from motocross and BMX bikers, who have a high rate of spleen injury and removal. Why? Because when they have accidents, their abdomens often crash into the handlebars of their bikes.
thym/o
roots
Def: thymus
Ex: thymoma, thymectomy
Notes: The thymus is an organ found at the base of the neck. Its name is derived from the herb thyme. Evidently, the organ looked like a bunch of thyme to the folks who first discovered it.
immun/o
roots
Def: immun/o
Ex: immunology, inmmunoglobulin
Notes: The immune system is the body’s defensive system against foreign invaders. Most people don’t realize that the skin is a layer of the immune system. It functions as a physical barrier between your vital organs and a world of organisms intent on causing harm to them.
-penia
suffix
Def: deficiency
Ex: cytopenia
Notes: -penia comes from a Greek word meaning “poverty” or “famine.” It is related to the English word penury, which means “poverty.” But that’s a word that doesn’t get used much these days.
