Choose the best location for obtaining a red bone marrow sample from a patient. 14) a) medullary cavity of femur c) hip bone b) frontal bone d) head of humerus

the hip bone

Explanation:

The bone marrow is divided into two; yellow and red bone marrow. The yellow bone marrow stores fats and contains mesenchymal stem cells which can develop into muscle cells or cartilage. The yellow marrow is located at the central cavities of long bones while the red bone marrow is located at the hip, sternum and humerus.

For a red bone marrow biopsy and aspiration to be done on a patient, the samples should be best obtained from the hip bone because it is a flat bone with soft tissues and no major organs and blood vessels are located.
