تعريف ومعنى "erythrocyte"

What is an "erythrocyte"?

An erythrocyte, also known as a red blood cell, is an essential component of the human body's circulatory system. They are specialized cells responsible for carrying oxygen from the lungs to all parts of the body and delivering carbon dioxide back to the lungs for exhalation. Erythrocytes contain hemoglobin, a protein that binds to oxygen, giving the cells their characteristic red color. Their unique biconcave shape allows for increased surface area, facilitating efficient gas exchange. Erythrocytes are produced in the bone marrow and circulate within blood vessels, playing a vital role in maintaining oxygen balance and supporting overall bodily functions.
