Red blood cells (blood cells) Red blood cells, also known as red blood cells, are often abbreviated as RBC in routine laboratory English. They are the most abundant blood cells in blood, the most important medium for vertebrates to transport oxygen through blood, and also have immune function. Mature red blood cells of mammals are seedless, which means that they have lost their DNA. Red blood cells also have no mitochondria. They release energy by breaking down glucose. When oxygen is transported, a part of carbon dioxide is also transported. It is dark purple when transporting carbon dioxide and bright red when transporting oxygen.
Red blood cells will be produced in bone marrow and begin to grow in white blood cells. After aging, red blood cells are easy to block blood vessels, so they will automatically return to the depths of bone marrow and be destroyed by white blood cells; Or when passing through the liver, it is decomposed into bile by Kupffer cells.
