The human body is incredibly resilient. When you donate a pint of blood, you lose about 3.5 trillion red blood cells, but your body quickly replaces them. You can even lose large chunks of vital organs and live. For example, people can live relatively normal lives with just half a brain). Other organs can be removed in their entirety without having too much impact on your life. Here are some of the non-vital organs.
Spleen
This organ sits on the left side of the abdomen, towards the back under the ribs. It is most commonly removed as a result of injury. Because it sits close the ribs, it is vulnerable to abdominal trauma. It is enclosed by a tissue paper-like capsule, which easily tears, allowing blood to leak from the damaged spleen. If not diagnosed and treated, it will result in death.
When you look inside the spleen, it has two notable colours. A dark red colour and small pockets of white. These link to the functions. The red is involved in storing and recycling red blood cells, while the white is linked to storage of white cells and platelets.
You can comfortably live without a spleen. This is because the liver plays a role in recycling red blood cells and their components. Similarly, other lymphoid tissues in the body help with the immune function of the spleen.

Not to crap on your post but I just couldn't resist.

(1,714 posts)--the spleen can apparently grow back. Mine was removed over 30 years ago (and I have never missed it!) Last year my primary care doc discussed having a pneumovax. I mentioned that I had had one before my spleen was removed and it must have worked because I've never had pneumonia. He seemed surprised, and said that possibly a had an extra spleen, or mine might have grown back.
