People can survive organ failure, a review explores how. Although organ failure can be fatal, your kidneys, heart, and liver are prepared for this catastrophe. Emerging research supports the finding that two cell populations quickly respond and work together to restore a non-functioning, or failing, organ. First, the surviving cells go into overdrive, working to keep the organ functioning while stem-like cells replace damaged tissue. A Review explores how this dual-response can save lives. Source 7u.
Of course the body springs into "Emergency mode" when your organs fail in some way; hence why we can survive for so long until the hospital. However sometimes despite the body's efforts it's simply just not enough and hopefully science finds a way to speed up this process to save more lives.
