Reconciliation of the general ledger to sub-ledgers is another type we will review. The general ledger (or simply ledger or G/L) is a collection of all balance sheet and income statement accounts. The general ledger also includes all journal entries posted to accounts.
Blood type (or blood group) is determined, in part, by the ABO blood group antigens present on red blood cells. A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). Blood group A individuals have the A antigen on the surface of their RBCs, and blood serum containing IgM antibodies against the B antigen. 2  Therefore, a group A individual can receive blood only from individuals of groups A or O (with A being preferable), and can donate blood to individuals with type A or AB.
There are four main ABO blood type groupings: A, B, AB, and O. These blood groups are determined by the antigen on the blood cell surface and the antibodies present in the blood plasma. Antibodies (also called immunoglobulins) are specialized proteins that identify and defend against foreign intruders to the body.ur blood is composed of blood cells and an aqueous fluid known as plasma. Human blood type is determined by the presence or absence of certain identifiers on the surface of red blood cells.
