Blood WBC or white blood cells are also known as leucocytes. These are the immune system cells that are involved in protecting the body against both infectious diseases and foreign invaders.
WBC in blood refers to white blood cells or leucocytes. The cells that are colorless, nucleated, and relatively low in number are called white blood cells.
The number of white blood cells per cubic milliliter of blood is about 5000-9000. The number of white blood cells is much lower than that of red blood cells.
The ratio of red blood cells to white blood cells is about 700: 1.
What is the normal value of WBC in the blood?
The normal number of WBCs in the blood is 4,500 to 11,000 WBCs in microliters (4.5 to 11.0 × 109 / L). The values may vary slightly between different labs.
