The two central organs of the immune system are the bone marrow and thymus gland. The bone marrow is responsible for producing all the blood cells, including the white blood cells that make up the immune system, while the thymus gland is where T cells mature and become functional. The other options are peripheral lymphoid organs that are also part of the immune system, but they are not considered central organs.
