The brain, heart, liver, intestinal/digestive system, etc. are the most important organs. There is a reason they are called "vital" organs. The lesser-known organs with funny-sounding names are generally the least important ones. (Pancreas, Spleen, etc.)

They're all vital in their own way.

* Heart/lungs function can be replaced by a bypass machine. * Musculoskeletal is unnecessary if you don't want to 'move' but this would include any form of communication at all making one a prison in one's body. * Urological system can be replaced by dialysis and catheters etc. * Reproductive system is necessary to reproduce without which species would die out, but we could get by day-to-day fine without it. * Skin is vital to maintain fluid balance (we'd dry out and die without it) and to prevent infection. * Gastrointestinal can be replaced by nutrition straight into the blood. * Endocrine system is really essential and difficult to completely replace. * Nervous system - I suppose we would cease to 'be' without it and it wouldn't matter about the other systems. They're all vital in their own way.
