Red blood cells have a lifespan of120 days.
Red blood cells, also known as erythrocytes, play a crucial role in transporting oxygen from the lungs to various tissues and organs throughout the body.
Their unique biconcave shape provides a larger surface area for gas exchange.
As they age, RBCs undergo changes that affect their flexibility and functionality, making their removal necessary to maintain the health of the circulatory system.
After this period, they are removed from circulation and broken down, primarily in the spleen.
The body continually produces new red blood cells to replace the old ones.
The process of erythropoiesis, controlled by the hormone erythropoietin, ensures a constant supply of new red blood cells to sustain proper oxygen delivery.
