Proteins produced by your white blood cells that help kill foreign invaders such as bacteria, viruses, fungus, and other harmful organisms.  Antibodies trigger other white blood cells to destroy these invaders.

  Single celled microorganisms that may cause infection.

  Brown liquid made in the liver that helps the body digest fat.

  Small pathways (like tunnels) within the liver that carry bile into a big duct or passageway called the common bile duct.  The common bile duct is connected to your small intestine and carries bile made in the liver to your small intestine.  In the small intestine, your bile helps to digest fats.

  A brown pigment (like a dye) that makes your bile and your stool (bowel movements) brown.  Bilirubin comes from old red blood cells that have died.  It is changed in the liver into a form that colors bile and makes stool brown.  When the liver doesn't work the bilirubin is not changed into this form, so the bile and the stool may be pale [..]

  The basic unit making up all living things.  Your body and your new liver are made up of billions cells with many different functions.

  Small hairs that line your respiratory passageways and help "sweep" out harmful organisms and particles before they reach your lungs.

  Cytomegalovirus, a normally harmless virus that lives in the environment and enters most of our bodies by the time we become adults.  We make antibodies to this virus and are not usually affected by it.  However, being immunosuppressed can result in the virus causing infections in the liver (CMV hepatitis) or in other organs of the body.  The [..]

  Watery (formless) bowel movements.  Soft, formed stool is not considered diarrhea.  Diarrhea can indicate infection in your intestines, an allergy or intolerance to something you are eating, or a side effect of some of your medications.

  Proteins made within cells.  Liver enzymes are made inside your liver cells and are known as SGOT (AST), SGPT (ALT) and alkaline phosphatase.  They are released into your bloodstream when rejection or hepatitis occurs and are measured by blood tests.
