Final answer:
The bone marrow aspirate for use with the angle system can be harvested from the Iliac Crest.
Step-by-step explanation:
The bone marrow aspirate for use with the angle system can be harvested from the Iliac Crest. In the past, bone marrow samples or transplants would require a procedure that involved inserting a large-bore needle near the iliac crest of the pelvic bones, which is located close to the body surface and relatively isolated from vital organs. Harvesting bone marrow from the iliac crest is preferred because of its accessibility.
