Red blood cells at work Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells also remove carbon dioxide from your body, transporting it to the lungs for you to exhale.
Red blood cells are made inside your bones, in the bone marrow. They typically live for about 120 days, and then they die.
The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Your heart is sort of like a pump, or two pumps in one. The right side of your heart receives blood from the body and pumps it to the lungs.
A blood cell, also called a hematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood. Major types of blood cells include; Red blood cells (erythrocytes) White blood cells (leukocytes)
What is the role of red blood cells in the blood? The red blood cells are highly specialized, well adapted for their primary function of transporting oxygen… The function of the red cell and its hemoglobin is to carry oxygen from the lungs or gills to all the body tissues and to carry carbon dioxide, a waste product of metabolism, to the lungs, where it is excreted.
