Red blood cells perform the most important blood duty. A single drop of blood contains millions of red blood cells which are constantly traveling through your body delivering oxygen and removing waste. If they weren't, your body would slowly die.
Red blood cells are red only because they contain a protein chemical called hemoglobin which is bright red in color. Hemoglobin contains the element Iron, making it an excellent vehicle for transporting oxygen and carbon dioxide. As blood passes through the lungs, oxygen molecules attach to the hemoglobin. As the blood passes through the body's tissue, the hemoglobin releases the oxygen to the cells. The empty hemoglobin molecules then bond with the tissue's carbon dioxide or other waste gases, transporting it away.
Over time, the red blood cells get worn out and eventually die. The average life cycle of a red blood cell is 120 days. Your bones are continually producing new blood cells, replenishing your supply. The blood itself, however, is re-circulated throughout your body, not being remade all of the time.
Since the human body is continually making more blood, it is safe for healthy adults to donate blood. The blood is then stored for use in emergency situations. Initially after giving blood, the donor may feel some momentary lightheadedness due to the loss of oxygen-rich red blood cells and blood sugar. The body quickly stabilizes itself.
The red blood cell carries oxygen from the lungs to the rest of the body.
Red blood cells because that is what carries oxygen throughout the body
Red Blood Cells
The four major components in blood are: -Plasma -Platelets -Red Blood Cells -White Blood Cells
Erythrocytes aka red blood cells, specifically the hemoglobin of the red blood cells
While they are very similar in size white blood cells are bigger while red bloods cells are much more numerous.
Red blood cells contain hemoglobin. These cells are also known as erythrocytes.

red blood cells
Red blood cells contain hemoglobin, but white blood cells do not
As the name says, red blood cells are found in the blood. If there is blood there, there is red blood cells.
The old red blood cells get replaced by the newly formed red blood cells.
