The Small Percentage of White Blood Cells
The immune system works round the clock to fight off microbes and protect you from diseases. It is natural for people to accept that the main soldier, the white blood cells, will account for a majority of the blood.
However, the reality is not the same. Blood cells cover only one percent of the cells in blood worth five liters in a healthy adult’s body. But there are adequate white blood cells to protect you from infection. In every microliter of blood, there are between 5,000 and 10,000 white blood cells.
