Because they do not have a nucleus in order to have more space to carry oxygen. Also red blood cells have a life span of 120 days, after that period they die and are reabsorbed by the the liver.
Erythropoietin, which is a hormone released by the kidneys, causes the creation of red blood cells in the bone marrow. These red blood cells are created from haemopoietic stem cells.
The Red Blood Cells remove wastes from your cells.
Blood containing red blood cells filled with oxyhemoglobin appears bright red.
Red blood cells contain hemoglobin, a protein that binds to oxygen. It is the iron in hemoglobin that gives red blood cells their red color. When oxygen binds to hemoglobin, the color appears brighter red.
Red blood cells contain a protein called hemoglobin, which is responsible for carrying oxygen from the lungs to the rest of the body. Hemoglobin binds to oxygen in the lungs, giving red blood cells their red color.

Depends on the cell. Red blood cells are redThere are two types of cells. Red Blood Cells and White Blood Cells.
blood is red due to the blood cells that form blood. there are also white blood cells but are not seen because of the value of the red blood cells of a greater number.
Erythropoietin, which is a hormone released by the kidneys, causes the creation of red blood cells in the bone marrow. These red blood cells are created from haemopoietic stem cells.
The number of white blood cells is out numbered bye the red making the blood the color that it is.
The Red Blood Cells remove wastes from your cells.
when a person has fewer red blood cells than normal his or her color is yellowish
Blood containing red blood cells filled with oxyhemoglobin appears bright red.
Hemoglobin carries the oxygen in the blood and it gives the red blood cells their color.
Red blood cells contain hemoglobin, a protein that binds to oxygen. It is the iron in hemoglobin that gives red blood cells their red color. When oxygen binds to hemoglobin, the color appears brighter red.
It is red, because in it, there is red blood cells, which is the color red.
Red blood cells are red because they contain a protein called hemoglobin, which binds to oxygen and gives the cells their red color. Brown blood may indicate that the blood has been exposed to oxygen for a prolonged period of time, causing the hemoglobin to oxidize and change color.
