where do you find red and yellow marrow?
bones
located in long bones are two distinctions of bone marrow (yellow and red). the yellow marrow has fatty connective tissue and is found in the marrow cavity. during starvation, the body uses the fat in yellow marrow for energy. the red marrow of some bones is an important site for blood cell production, approximately 2.6 million red blood cells per second in order to replace existing cells that have been destroyed by the liver. here all erythrocytes, platelets, and most leukocytes form in adults. from the red marrow, erythrocytes, platelets, and leukocytes migrate to the blood to do their special tasks.
human musculoskeletal system
the outer shell of the long bone is made of cortical bone also known as compact bone. this is covered by a membrane of connective tissue called the periosteum. beneath the cortical bone layer is a layer of spongy cancellous bone. inside this is the medullary cavity which has an inner core of bone marrow, it contains nutrients and help in formation of cells, made up of yellow marrow in the adult and red marrow in the child.
