Bone marrow, thymus, and liver
Primary lymphoid organs in fetus
Bone Marrow:
Bone marrow is the spongy tissue found inside bones, and it is responsible for producing several types of blood cells. It produces red blood cells, which carry oxygen throughout the body, white blood cells, which fight infections, and platelets, which help to clot the blood. Bone marrow can also produce stem cells, which are cells that can develop into different types of cells.
Thymus:
The thymus is a small gland located behind the breastbone. It plays a vital role in the immune system, specifically in the development and maturation of T-cells. T-cells are a type of white blood cell that helps to fight infections and other foreign substances in the body. The thymus produces and releases hormones that help to stimulate the growth and development of T-cells.
Liver:
The liver is a large organ located on the right side of the abdomen. It has over 500 functions in the body, including producing bile, which helps in the digestion of fats, and storing glucose, which is used by the body for energy. The liver also produces several important proteins, including albumin, which helps to maintain fluid balance in the body, and clotting factors, which help the blood to clot. Additionally, the liver helps to break down and remove toxins and other harmful substances from the body.
