General and Sub-ledgers As the main accounting record, the general ledger is created first. It is organized by account, with each numbered in a series, and each number is typically five to six digits long.
Paucity of vasculature. In adults, red bone marrow is primarily found in the flat bones, such as the pelvic girdle and the sternum. In children, it is found in the medullary cavity of the long bones, such as the femur.
Bone marrow is where blood cell production takes place and it has a generous blood supply. When a bone breaks, significant bleeding may be expected. Long bones like the humerus (upper arm bone), femur (thigh bone), and pelvic bones can cause the body to lose 10% or more of its blood supply.
