About the full form of RBC?
The full form of the RBC is the red blood cells. It is also called erythrocytes. Erythrocytes are human biconcave and nucleus-free cells; they are also recognized as erythrocytes. Erythrocytes contain an iron-rich protein called hemoglobin, which gives the blood-red color. The most common blood cells formed in the bone marrow are erythrocytes. Hemoglobin is mainly made up of iron, mixed with oxygen, which gives the blood a reddish color. It occupies 40-45% of the total volume of blood.
About RBC
Few points of RBC
1. The ratio of the volume of blood that includes all red blood cells is called the hematocrit.
2. About 0.5 billion erythrocytes contain a drop of blood.
3. There are about 40 platelets and one white blood cell for every 600 erythrocytes.
4. Erythrocytes are constantly being produced in the bone marrow because they remain in the blood for about 120 days before the spleen or liver excrete them.
5. The bone marrow produces enough erythrocytes to make up for the deficit by removing old erythrocytes.
6. A tiny, round, disc-shaped cell that does not contain a nucleus is a mature human erythrocyte. On a peripheral blood smear, it is about 7-8 micrometers in diameter.
7. To move through the smallest blood vessels or blood capillaries, they have a flexible membrane that allows them to change their appearance.
8. In an adult, there are around 4.5 to 6 million erythrocytes per cubic millimeter of blood volume.
Importance of RBC
It is believed that red blood cells play a very important role in our body, the main function of which is to carry oxygen into body tissues in exchange for carbon dioxide carried by the lungs.
You should also know that there is an element called a hemo cytoplast that takes about 2 days to make red blood cells in our bodies. Where you'd be quite surprised to learn that the body produces up to 2 million red blood cells every second. Blood contains 45% red blood cells, 1% white blood cells and platelets, and 55% plasma, which mainly helps our body function properly.
Functions of RBC
1. The respiratory pigment that binds to oxygen or carbon dioxide molecules is an erythrocyte.
2. It involves the transport of oxygen to various tissues and organs in the human body.
3. It also extracts carbon dioxide, which is replenished in the lungs from multiple organs and tissues.
RBC lifespan
1. RBC has a lifespan of 100-120 days.
2. They are excreted through the circulatory system when their life cycle is complete.
3. The lifespan of erythrocytes is shortened when a person suffers from chronic diseases.
