red blood cell
Hemoglobin's circular vessel
A red blood cell is a disc-shaped cell in the blood that carries oxygen from the lungs to the body's tissues and returns carbon dioxide for exhalation.
Red blood cells give blood its color—they contain hemoglobin, an iron-rich protein that binds oxygen.
Also called erythrocyte in medical contexts.
