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

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
