Final answer:
Erythrocytes, also known as red blood cells, are vital for oxygen transport in the body due to their unique structure and hemoglobin content.
Explanation:
Erythrocytes (Red Blood Cells) are specialized cells that circulate in the body to deliver oxygen to tissues. They are small biconcave cells that do not contain a nucleus, allowing them to have flexibility and a larger surface area for gas exchange. Erythrocytes contain hemoglobin, a protein that binds to oxygen and transports it throughout the circulatory system.
