GENERAL HISTOLOGY

Detailed explanation-1: -White blood cells are immune system cells. They are like warriors waiting in your blood stream to attack invaders such as bacteria and viruses. When fighting an infection, your body produces more white blood cells.

Detailed explanation-2: -One of the most important players in our immune systems is the white blood cell, also called a leukocyte. Leukocytes patrol the blood and tissues throughout the body in search of intruders. When they detect a foreign substance, they send out signals and launch an immune attack.

Detailed explanation-3: -Stem cells in the bone marrow are responsible for producing white blood cells. The bone marrow then stores an estimated 80–90% of white blood cells. When an infection or inflammatory condition occurs, the body releases white blood cells to help fight the infection.

Detailed explanation-4: -If you had no white cells, you would get lots of very serious infections. White blood cells can find germs that enter your body and destroy them, which keeps them from making you sick. Some white blood cells make antibodies, which are special molecules that can stick to germs and make them harmless.
