red blood cell
A red blood cell (RBC), or erythrocyte, is a blood cell that carries oxygen from the lungs to body tissues and transports carbon dioxide back to the lungs using the protein hemoglobin.
Red blood cells (RBCs), also called erythrocytes, are the most abundant cells in human blood and are responsible for transporting oxygen throughout the body. They are produced in the bone marrow through a process called erythropoiesis and develop from the myeloid lineage of blood-forming cells. Red blood cells contain hemoglobin, an iron-containing protein that binds oxygen and gives blood its red color. Mature human RBCs lack a nucleus, allowing more space for hemoglobin and efficient gas transport. Abnormalities in red blood cell number, structure, or function can lead to disorders such as anemia, polycythemia, and inherited conditions affecting hemoglobin.
Red blood cells are the cells in your blood that carry oxygen around the body. They contain hemoglobin, which holds oxygen and gives blood its red color.
• Also called RBCs or erythrocytes • Most common type of blood cell • Produced in bone marrow • Develop from the myeloid lineage • Main function is oxygen transport • Carry oxygen using hemoglobin protein • Help remove carbon dioxide from tissues • Abnormal RBC levels can cause conditions such as anemia
