Red blood cells, also known as erythrocytes, are cells in the bloodstream that are responsible for carrying oxygen from the lungs to the body’s tissues and removing carbon dioxide from those tissues to be exhaled.
They contain a protein called hemoglobin that binds to oxygen and helps transport it throughout the body.
Red blood cells are produced in the bone marrow and have a unique shape that allows them to flow smoothly through blood vessels.
Their function is essential to maintaining proper oxygen levels and overall health.
