Detailed explanation-1: -Leukocytes are found in lots of places, including your spleen, an organ in your belly that filters blood and helps fight infections. Leukocytes also can be found in bone marrow, which is a thick, spongy jelly inside your bones.

Detailed explanation-2: -Specialized innate immune cells like B cells, natural killer (NK) cells, and macrophages populate locations within the spleen. Specifically, the spleen is a crucial organ for peripheral immune tolerance, complementing central immune tolerance.

Detailed explanation-3: -Leukocytes in the spleen include various subsets of T and B cells, dendritic cells (DCs) and macrophages that exert discrete functions.

Detailed explanation-4: -The spleen is a small organ inside your left rib cage, just above the stomach. It’s part of the lymphatic system (which is part of the immune system). The spleen stores and filters blood and makes white blood cells that protect you from infection.

Detailed explanation-5: -White blood cells, also known as leukocytes, are responsible for protecting your body from infection. As part of your immune system, white blood cells circulate in your blood and respond to injury or illness.
