what is the lifespan of rbc


The lifespan of red blood cells (RBCs), also known as erythrocytes, varies depending on the species. In humans, the average lifespan of an RBC is approximately 120 days. However, this can vary due to various factors such as age, health conditions, and genetic disorders.

During their lifespan, RBCs transport oxygen from the lungs to the body's tissues and carbon dioxide from the tissues back to the lungs to be exhaled. After about 120 days, old or damaged RBCs are removed from the bloodstream and broken down by the liver and spleen, and their components are recycled to create new RBCs.
