thymus

spleen
C
tonsils
D
lymph nodes
Explanation: 

Detailed explanation-1: -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-2: -The spleen is located in the upper left part of the belly under the ribcage. It helps protect the body by clearing worn-out red blood cells and other foreign bodies (such as germs) from the bloodstream.

Detailed explanation-3: -It is the largest organ of the lymphatic system-the circulatory component of the immune system. It recycles iron, destroys old red blood cells, and stores white blood cells and platelets, the components of the blood that help stop bleeding.

Detailed explanation-4: -The spleen filters blood in much the way that the lymph nodes filter lymph. Lymphocytes in the spleen react to pathogens in the blood and attempt to destroy them. Macrophages then engulf the resulting debris, the damaged cells, and the other large particles.

Detailed explanation-5: -It is the largest of our lymphatic organs. The spleen does many things as it filters and monitors our blood. It contains a range of cells, including macrophages – the body’s garbage trucks. It also produces and stores many cells, including a range of white blood cells, all of which are important for our body’s defence.
