Erythrocytes are known more commonly as:

Erythrocytes are more commonly known as red blood cells. These cells are crucial components of the blood, responsible for transporting oxygen from the lungs to the tissues and carrying carbon dioxide back to the lungs for exhalation. The name "erythrocyte" derives from the Greek words 'erythros' meaning red, and 'kytos' meaning cell, which reflects their primary function and appearance.

In addition to their role in gas exchange, red blood cells contain hemoglobin, a protein that binds to oxygen. This characteristic imparts their distinct red color and highlights the importance of erythrocytes in maintaining the body's oxygen supply and overall metabolism.
