Video: Heart and circulatory system. Your heart is a pump. It's a muscular organ about the size of your fist and located slightly left of center in your chest.

Together, your heart and blood vessels comprise your cardiovascular system, which circulates blood and oxygen around your body. Your heart pumps about 5 quarts of blood every minute.
Most tests measure hepatocellular damage rather than function, so they are rather misnamed. True liver function tests (LFTs) are those that measure synthesis of proteins made by the liver (albumin, clotting factors) or the liver's capacity to metabolise drugs. LFTs are not specific to specific systems or disease processes, yet abnormalities may indicate significant or serious disease. Interpreting abnormal LFTs and trying to diagnose any underlying liver disease is a common scenario in Primary Care. Single abnormalities in LFTs are difficult to localise and diagnose.
