When bacteria enter our body.

Our body is beset with bacteria all the time. There is such bacteria in our body which keeps our immune system more strong. Our immune system keeps us safe and our immune system is good for us. If we had not had an immune system, we would have died from a small wound, so our immune system is responsible for our survival. Whenever a deadly bacteria enters our body, our immune system kills it and protects us.

There is a military area inside our body which protects us from any bacteria or virus. The guards, Soldiers, Intelligent Teams, Baker Teams, Weapon Factories in our body, and all these are called the Immune System of our body.

Our immune system protects us from infection, disease, disorder. If our body gets bacteria or virus, then our immune system starts working fast.

When we apply a blade to the arm and in no time it runs into bacteria and starts doubling the bacteria from our body, then our body's protector is eradicated from both macrophysis and water, when the bacteria is not gone it happens. When this happens, our immune system orders neutrophils to eliminate bacteria, then our body starts warming up and we call it fever. Fever is one such symptom that shows that now our immunity is ending. Fever is right for us,

Or to kill.

When both neutrophils and macrophysics cannot kill bacteria, they both lead to the head of our immune system, called a dendritic cell. Dendritic bacteria give information to T cell. Then T cell training takes place and the T cells that pass the training go to kill the bacteria. Passed T cells double themselves. Double-stranded cells do not go to kill bacteria, but T cells store information of the bacteria with which those bacteria enter our body, so our immune system hopes to kill it. It is also called as memory T cell.

The cell which goes to kill the bacteria also tells about the B cell bacteria and the B cell also goes to kill the bacteria, those cells also double themselves, and with their own weapons that The bacteria begin to kill, that weapon is called an antibody.

T cells, B cells, neutrophils and macrophysics all kill bacteria and eventually the immune system wins. When bacteria in our body die, neutrophils, macrophyses, T cells and B cells kill themselves so that our body's immunity is not wasted and everything becomes normal. But the memory T cells that were twice the T cells do not die and survive in our body.

When such bacteria re-enter our body, memory T cells destroy them quickly. And our body becomes free from bacteria. But when another new bacterium enters the body, the whole process occurs again.

When the virus enters our body, it enters our langs directly and that virus tries to enter the cell from our langs and starts making its own DNA. According to scientists, 37.2 trillion cells are present in our body, and that is a security system made in each cell, which helps us in doing everything.

The cells present in our body have different ways of doing their work. When we drink water or eat food, that water or food goes directly to our liver, the food that goes to the liver is from our cells. When we drink water, that water does not go to the langs and goes directly to the liver, then cells are present to send those water to the liver, which send water or any substance or substance to the liver itself. There are different cells for every work of our body and all work is different.
