Red blood cells might have the most important cell job in your body. Red blood cells give you oxygen, and oxygen gives fuel to all your body cells for energy. What if red blood cells weren’t there?

= Why do Red Blood Cells change color? =

The reason why red blood cells change color is because of hemoglobin. Hemoglobin is an iron containing protein it’s important because it holds onto oxygen molecules. Without hemoglobin our red blood cells will not give us oxygen. In this picture of hemoglobin you can see is a chain of iron. Hemoglobin makes it red because when hemoglobin combines with oxygen, the cells become bright red. Without oxygen, the cells are dark red.

Here is how red blood cells move in your body. First red blood cells are carried in this liquid called plasma. Plasma is made out of some dissolved proteins, but mostly water about ninety percent. Red blood cells are always on the move they can't stop or our oxygen will stop. Red blood cells every second 2 million red blood cells die in your body. Without the cells on the move our body won't let the protein the red blood cells give us to function very well, oxygen is very big for our body. In this picture it shows red blood cells working together with white blood cells, and Platelet their all in plasma moving all together one by one.

= How do Red Blood Cells Function and how are they Structured? = Red Blood cells also called Erythrocytes are the most Abundant cell type in blood. Erythrocytes are the red blood cells that Transport oxygen to body cells, and carry carbon dioxide to your lungs. Hemoglobin is the protein inside red blood cells that carries oxygen. Red blood cells remove carbon dioxide from your body transporting it to the lungs for you to exhale. Give fuel to all your body cells for energy. They are also shaped as a donut they are shaped as a donut because it’s easier to pick up oxygen molecules.

If we didn’t have red blood cells we wouldn’t be able to fight off a disease called sickle cell anemia. Sickle Cell Anemia is a group of disorders that cause red blood cells to become misshapen and break down. Hemoglobin that are in red blood cells are a victim in the disease because Sickle cells block the blood flow making the shape of the red blood cells strand inside instead of the dots. The image below shows a normal red blood cell and show an abnormal red blood cell.

Furthermore, Red blood cells have the hardest and most important cell job in a humans body. Giving us energy to keep our body healthy, they are structured like a donut because it stores all the energy in it for our bodies. It also can fight off the disease called sickle cell anemia that causes red blood cells to become misshapen and break down.
