Blood cells are very important for the proper functioning of the body system, and there are three basic types of cells found in blood. These are classified into
Erythrocytes – red blood cells
Leukocytes – white blood cells
Thrombocytes – platelets
These types of cells found in blood together compose 45 percent of the total tissue volume in the blood. The remaining percentage is made up of plasma. These components are all present in all human beings and there is not regional or population difference.
Erythrocytes (Red Cells)
These types of cells found in blood are large with no nuclei. They contain about 40 percent of the blood volume found in the body. Their primary function is the transportation of oxygen to various sections of the body from the lungs. Red blood cells are created from the stem cells of bone marrows with close to 3 million cells produced within a second. Hemoglobin is the main constituent of the red blood cell as it comprises 95 percent molecule content in the red blood cell. There are more than 250 million iron rich molecules of hemoglobin in the red blood cells. A deficiency of these types of cells found in blood can lead to anemia.
Leukocytes (White Cells)
These are very small in composition compared to RBCs in the body. In adults, they make up about 1% of the total blood cells found in the body. These types of cells found in blood, can equally be found in other areas of the body such as the lymph glands, liver, and spleen. They are equally created from the same cells that produce RBCs in the bone marrow. But some other white blood cells are produced at the thymus glands. They are very active in the body’s immune system and some of them react faster than other types of cells found in blood. They find, identify, and incapacitate unrecognized proteins found on fungi, viruses, and bacteria and ensure that they can be removed from the body.
Some other WBCs such as macrophages and granulocytes then come to the arrested proteins in order to destroy the cells they have formed. These types of cells found in blood equally play the role of removing dying or dead blood cells including foreign matters like asbestos and dust from the body. The RBCs live longer than the WBCs as they can stay in the body for 4 months before they are reproduced in the spleen. On the other hand, the WBCs last for only three days, though very few can stay up to months in the body before they are recycled.
These types of cells found in blood do not have nuclei. They are agents responsible for blood clotting in wounds. Before clotting can effectively occur, there are several factors that should interact. These factors interact by triggering one another. Platelets do not always occur throughout the day. Some periods they might be effective while in some other periods, they might not. However, they are more effective in the morning than at any other periods.
