Where are red blood cells produced?
Quick Answer
Red blood cells are produced in the red bone marrow. In adults, this is mainly found in bones such as the pelvis, sternum, ribs, and vertebrae.
The Full Story
Red blood cells are formed in red bone marrow through a process called erythropoiesis. In adults, active marrow is concentrated in flat bones and in the ends of some long bones. These cells carry oxygen using hemoglobin and are continually replaced because they have a limited lifespan of about 120 days. The kidneys help regulate red blood cell production by releasing erythropoietin when oxygen levels are low.
