Red blood cell - Wikipedia
Human red blood cells are produced through a process named erythropoiesis, developing from committed stem cells to mature red blood cells in about 7 days. When matured, in a healthy individual these cells live in blood circulation for about 100 to 120 days (and 80 to 90 days in a full term infant). [ 62 ]

2024年4月23日 · The red blood cells or erythrocytes are red-colored cells having a biconcave shape. They are flattened discs lacking nuclei and cytoplasmic organelles, containing the red protein hemoglobin for gas transport, primarily oxygen and some carbon dioxide. It measures 7.5 µm in diameter with 2.6 µm thick at the rim and 0.8 µm thick at the center.
