Blood Bank in Human Body is (A)Spleen (B)Lungs (C)Heart (D)Liver

Answer:- (A) Spleen

It is located under the lungs and is essential for blood purification and emergency storage of blood cells, such as during a hemorrhagic shock.

Behind the stomach and beneath the lungs is the spleen. It is around 5 inches broad and 6 ounces in weight. The spleen stores blood and aids in battling severe illnesses. 

The spleen is a blood reservoir that also cleans the blood (by filtering out germs and viruses while it creates white blood cells to combat illness). It is covered by the rib cage and is part of the lymphatic system.
