a combination of several drugs taken in a daily regimen to combat HIV and commonly referred to as a "cocktail" although it is administered in pill form
|
|

|
Leukocyte
|
white blood cells involved in phagocytosis, includes neutrophils & polymorphic cells

|
Leukocytosis
|
an abnormal increase in white blood cells indicating infection or inflammation
|
|
T-lymphocyte

|
Immunity
|
the ability of the body to defend itself against infectious agents, foreign cells, and even abnormal body cells

formed when connective tissues anchor together adjacent structures during healing
