Every minute of the day, we are bombarded with an unlimited number of microorganisms from viruses, bacteria, fungi, and more. Each of these microorganisms could harm our health and even kill us if we did not have a robust immune system that calms down these invaders and neutralizes them. 

​

The immune system is a complex network of cells, organs, and tissues that work together to destroy foreign cells or particles, thus keeping you healthy.  One part of this complicated immune system is white body cells.

​

There are two types of white blood cells: lymphocytes and phagocytes. Lymphocytes are more commonly known as B-cells and T-cells, and they destroy antigens (toxins or harmful foreign substances). They also help your body remember these foreign substances so that your immune system can respond quickly and appropriately when it detects another invasion. Phagocytes help absorb and neutralize the invaders, preventing them from spreading and causing more damage.

​

In addition to protecting your body against toxic invaders, your immune system is responsible for detecting and eliminating cells that aren't working correctly. Once found, the immune system initiates apoptosis, or cell death so that the defective cells do not multiply and form tumors.
