I heard it in a movie and its bugged me ever since
The spleen is an organ that functions to destroy old blood cells and it also holds a small reserve of blood that it can supply to the body when needed.
I have a sister-in-law who had to have a malformed speen removed as a child. This has always been a concern whenever she has had surgery since without the speen she lacks the extra reserve of blood that most people have.
For some odd reason, I thought the spleen was the liver... wow, you can tell I never passed the human bio module in science!
It has a pretty cool name for an organ though. It makes me think of an episode of 'Invader Zim'
"Gah! My Spiggly-spooch!"
I thought it was your backbone for some reason.. I guess not. that picture just taught me something new,.. yay!
This is a picture of where it is
