That's correct. Red blood cells (RBCs) are primarily produced in the bone marrow of long bones like the femur and the humerus in adult human beings. The bone marrow contains stem cells that differentiate into specialized blood cells, including RBCs.
Erythropoiesis, the production of red blood cells, occurs primarily in the bone marrow of human adults.
sternum. These sites are commonly used for collecting bone marrow samples in adults due to their accessibility and the presence of a rich source of bone marrow in these areas.

the yellow marrow cavity
In the marrow cavity of an adult humerus, you would typically find yellow bone marrow, which consists mostly of adipose tissue. Yellow bone marrow stores fat and does not actively produce blood cells unless needed in times of severe blood loss or specific medical conditions.
Yellow bone marrow mostly stores and is made up of fat cells. The yellow bone marrow makes up about half of the adult human bodies bone marrow.
There is more than one bone where red marrow is found in the adult. At birth, all bone marrow is red. With age, more and more of it is converted to the yellow type.Adults have on average about 2.6kg (5.7lbs) of bone marrow, with about half of it being red. Red marrow is found mainly in the flat bones such as hip bone, breast bone, skull, ribs, vertebrae and shoulder blades, and in the cancellous ("spongy") material at the proximal ends of the long bones: the femurs and humeruses.
Bone marrow in an adult, bone marrow and spleen in an infant, spleen and liver in a fetus.
in adulthood, the red bone marrow is in the shafts of most long bones.
This substance is called marrow. Red marrow is found in most bones of children, and is where red and white blood cells are made and mature. Yellow marrow is found in most adult bones, and is mostly composed of fat. The red marrow in childrens bones is slowly converted to yellow marrow as we age. In a middle-aged adult, usually only flat bones still contain red marrow.
