Answer 2

spleen.

Spleen is a sponge like organ located in the left upper aspect of the abdomen

In fetal life and in some special situations it does the job of production of RBCs/Blood.

And in normal physiology it does have a pool of blood which can be readily mobilised in case of need.

Hence it just functions like a bank!
