What different types bone marrow does the human body have?

The human body has two main types of bone marrow: red marrow and yellow marrow. Red marrow is responsible for producing blood cells, including red blood cells, white blood cells, and platelets, and is primarily found in the flat bones and the ends of long bones. Yellow marrow, which mainly consists of fat cells, serves as a storage site for fats and can be converted back to red marrow if needed, such as during severe blood loss or anemia. In adults, red marrow is mostly found in the pelvis, sternum, and ribs, while yellow marrow is more prevalent in the long bones of the limbs.
