[|Bone marrow] is classified as a soft tissue located in the interior of hollow bone. Marrow in adult large bones produce blood cells. There are two main types of bone marrow, red bone marrow and yellow bone marrow. red and white blood cells are present in red bone marrow and white blood cells can be found in yellow bone marrow. Yellow bone marrow receives its color from the increased number of fat cells it contains. Numerous blood vessels and capillaries are present in both forms of bone marrow. Babies are born with all red bone marrow and few, if any, yellow marrow cells. With an increase in age there is also an increase yellow marrow. Flat bones, hip bones, skull, and verterbrae primarily contain red bone marrow cells. Yellow bone marrow can be found mostly in the hollow interior of [|long bone] such as the femur and humerus. The beauty of marrow can be seen when the body suffers from a severe loss of blood. When this blood loss occurs the body converts yellow bone marrow into red bone marrow in order to increase the production of blood cells. Yes. Bone marrow can be effected by several factors including infections and malignancies. [|Tuberculosis] is an example of an infection that effects bone marrow. It decreases the amount of blood cells and platelets produced by the body. A diagnosis is usually obtained by a [|bone marrow aspiration]. In a bone marrow aspiration a hollow needle is used to obtain a sample red bone marrow from the crest of the ilium while the patient is under some form of anesthesia. Radiation exposure and/or chemotherapy can kill the rapidly dividing cells of bone marrow, resulting in a weakened immune system. Yes. Modern bone marrow transplants are very important surgeries that require a patient and a donor. the amount of patients in need of bone marrow is constantly increasing while the amount of donors are steadily decreasing. However, a bone marrow transplant is only effective if both the donor and the recipent are blood matches. The bone marrow transplant, contrary to modern myth, gives minimal discomfort to the donor. Transplant is not the only way to treat a person in need of bone marrow. Doctors can perscribe certain drugs that stimulate the production and release of stem cells of bone marrow intol circulating blood. The [|stem cells] are filtered out of the body using an IV. This procedure is similar to the donating of blood platelets and cells. Transplants are mostly performed under severe conditions. In this procedure the patients blood cells are killed by drugs and replaced with new stem cells. samples obtained through aspiration.

It is a great source of protein and monosaturated fat. Both of which help reduce the risk of [|cardiovascular disease.]Bone marrow is commonly consumed in European countries. flickr.com
