Living cells

T cells -- special forces in the human body

As a kind of white blood cells, T cells have an irreplaceable role, they are like the body's special forces, combat effectiveness.
They are born in the human bone marrow, and then they go to the human thymus where they are trained for a period of time. When they go out of the thymus again, they become a special soldier who can fight at any time.

T cells do not like other white blood cells, as long as it is a virus, regardless of 3721, together to fight. T cells are selectively attacking a particular virus, and usually only one of the countless T cells in the body responds. They really hit the spot.
The liaison soldiers on the battlefield dendritic cells

Dendritic cells are unique in appearance, like clawed clowns. Normally, they patrol around the body like patrols. Once they find the virus, they pounce on it, swallow it quickly, process it in the body, extract the virus's signature "fragment" and carry it on their shoulders, and then they begin a long journey to find and contact T cells that can deal with the virus.
This miraculous function of dendritic cells in the body was first discovered by a scientist named Ralph Steinman. On October 3, 2011, the Caroline Medical College in Sweden announced that Ralph Steinman won half of the 2011 Nobel Prize in Physiology or Medicine, and the other half was won by two other scientists. The three of them discovered the key principle of activation of the immune system, which revolutionized the understanding of the immune system.

The "missile bank" in the human body -- B cells

T cell is very important because it can open the human body to deal with the virus's missile bank. So what is the missile store? It's B cells.

Shortly after the virus invaded the body, a particular B cell actually got some information about the virus through other channels, but it didn't do it. Why? It turns out that it needs to wait for T cells to exchange information with it and make final confirmation.

Well, if that B cell has been activated by T cells, what will it do next? Well, like T cells, the first thing to do is to split up quickly and replicate a large number of B cells in a short time. These B cells begin to grow slowly, because they're constantly building a lot of "missiles" in their stomachs, and they're loaded with missile B cells, and they look fat, so, people. The B cells are called plasma cells.

The next step is to launch! In one second, a B cell can launch about 2000 missiles. And these missiles are called antibodies.

Natural killer cell

Natural killer cells, a type of white blood cells, are loyal guardians of the human body, whose main task is to mend the wound by destroying cells that have been infected by the virus, thereby killing the virus in the "cradle".
In addition, tumor cells in the body are also the target of their pursuit. The weapon used by natural killer cells is perforin. When it sprays perforin on the cells, it can make a small hole in the cells, thereby destroying the cells and the viruses in the cells.

The seventy-two major cells -- monocytes

Mononuclear cells are the largest blood cells in the blood. Like Monkey King, they transform and are also very athletic and can run away from home. It can not only engulf germs, but also remove damaged and senescent cells and debris.
If there's inflammation somewhere in the body, then there's work for the monocytes, which quickly accumulate into the infected tissue within eight to twelve hours.
Human scavenger - macrophages

When a monocyte runs away from the blood and comes out of the blood vessels and into other tissues of the body, the size of the monocyte increases, up to 50-80 microns in diameter. At this point, it is not called a monocyte. It becomes a more powerful human fighter - macrophages!

Macrophages are scavengers who keep cleaning our bodies, swallowing the tiny dust that enters our lungs. It is because of the hard work of the macrophages that our lungs are not polluted by countless dust.
It also swallows those dead cells, such as dead red blood cells. When you are injured, the small blood vessels in your skin break down, and the red blood cells flow out of the blood vessels. Red blood cells are valuable in blood vessels, but they do not have any advantages outside the blood vessels. But there is no need to worry that the elimination of dead cells will be done by macrophages.
If busy, macrophages will summon many of their companions and fight together. As powerful guardians of the human body, macrophages can swallow up a large number of bacteria, and eventually they die from their own digestive mixtures.
