Detailed explanation-1: -In addition, macrophages play an important role in eliminating diseased and damaged cells through their programmed cell death. Generally, macrophages ingest and degrade dead cells, debris, tumor cells, and foreign materials.

Detailed explanation-2: -The key functions of the lymphatic system: Drains excess fluids and proteins from tissues all around the body and returns them back into the bloodstream. Removes waste products produced by cells.

Detailed explanation-3: -The physical organization of the spleen allows it to filter blood of pathogens and abnormal cells and facilitate low probability interactions between antigen presenting cells (APCs) and cognate lymphocytes. APCs unique to the spleen regulate the T and B cell response to these antigenic targets in the blood.

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.
