IMMUNOLOGY

Detailed explanation-1: -The spleen controls the level of white blood cells, red blood cells and platelets (small cells that form blood clots). It screens the blood and removes any old or damaged red blood cells. If the spleen doesn’t work properly, it may start to remove healthy blood cells.

Detailed explanation-2: -An organ that is part of the lymphatic system. The spleen makes lymphocytes, filters the blood, stores blood cells, and destroys old blood cells. It is located on the left side of the abdomen near the stomach.

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 white pulp (WP) is the primary immunologic region of the spleen in both species; however, the WP makes up less than a quarter of splenic tissue. The red pulp (RP) makes up the majority of the tissue and has an immune function distinct from that of the WP.

Detailed explanation-5: -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-6: -The spleen also removes unhealthy, old, and misshapen red blood cells from circulation. Red blood cells carry oxygen throughout the body and remove carbon dioxide (a waste product). These disc-shaped cells are filtered by the spleen based on their physical characteristics.
