The lifespan of red blood cells is 120 days. That is, after 120 days, the old red blood cells in the blood disappear and they are replaced by new red blood cells.   The color of our blood is red because of red blood cells. In fact, a protein called hemoglobin is found in red blood cells and this protein is responsible for giving red color to the Red Blood Cells and to the Blood also. Red blood cells, also known as erythrocytes, have several important functions in the body: Transport oxygen : Red blood cells carry oxygen from the lungs to the body's tissues through the circulatory system. This is possible because red blood cells contain hemoglobin, an iron-rich protein that binds to oxygen. Hemoglobin also gives red blood cells their red color. Remove waste : Red blood cells also transport waste products, like carbon di...
