Erythrocytes

Erythrocytes, commonly known as red blood cells, are vital components of blood responsible for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide back to the lungs for exhalation. They contain a protein called hemoglobin, which binds to oxygen, giving them their red color. Erythrocytes are produced in the bone marrow and have a lifespan of about 120 days. Their shape, which is like a doughnut without a hole, helps them move easily through blood vessels. Maintaining a healthy erythrocyte count is essential for overall health, as it supports energy levels and proper organ function.
