MICROANATOMY

Detailed explanation-1: -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. The spleen is part of the lymphatic system, which is an extensive drainage network.

Detailed explanation-2: -Red pulp: The red pulp acts like a filter. It removes waste from the blood and gets rid of old or damaged blood cells. Red pulp also destroys bacteria and viruses.

Detailed explanation-3: -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-4: -The spleen is quite a large organ. In CLL, it sometimes becomes bigger and can cause problems. The spleen’s normal job is to filter the blood and to destroy and break down worn out red blood cells.

Detailed explanation-5: -Unlike lymph nodes, the spleen possesses only efferent lymphatic vessels, because it only filters blood instead of lymph fluid. The splenic artery forms its primary blood supply.
