I would assume that blood, within us, is only good for so long but, I could be wrong. Also, if it does become "bad", where does it go? How do we get rid of "garbage blood"?
Yes, blood does have an expiry date. Red blood cells have a lifespan of approximately 120 days, after which they are broken down and replaced by new cells. Platelets have a shorter lifespan of only 5-9 days. Plasma, the liquid component of blood, can be frozen and stored for up to a year, but after that it is no longer viable for transfusion.
As blood cells approach their expiry date, they become less efficient at carrying oxygen and nutrients throughout the body. This can lead to fatigue and other symptoms. The body's immune system also recognizes old blood cells and begins to break them down, which is why regular blood donations are needed to replenish the supply.
The expiry date of blood is typically determined by the blood bank or donation center where it is collected. They use various tests and guidelines to determine the viability and safety of the blood, including the age of the donor and any potential health risks.
No, there is no way to extend the expiry date of our blood. However, maintaining a healthy lifestyle and staying hydrated can help ensure that our blood cells are as efficient as possible during their lifespan.
Receiving expired blood during a transfusion can be dangerous, as the expired blood cells may not function properly and could potentially cause adverse reactions in the recipient. This is why strict guidelines and regular testing are in place to ensure the safety and efficacy of donated blood.
