Inside the Human body
The human body has the functions of afortress. Its job is to keep out invaders and eliminate any intruders. The bodyconsists thousands of different types of cells that each of which has its ownspecial jobs. When an invader has entered into the body, Lymphocytes (B-cells)when activated to produce huge numbers of themselves and they move in to theattack. However, they can only attach to bacteria that have certain markers andproduce antibodies. It all goes well; the antibodies from the lymphocytes willdeactivate the bacteria. After the actual procedure the bacteria dies and it isdisposed of later. Once the bacteria have been marked and if it has not beendestroyed; a cell called Phagocyte engulfs the marked bacteria. The Phagocyteacts as a holding cell until the next cell comes. It is also possible for thephagocyte to destroy the invader, but this does not happen if the bacteria aretougher. The name called T-cells is the killer of the subject. Killer T-cells,their job is to directly attack the invader. The T-cells kills itself, thephagocyte and the bacteria.
After the bacteria have beendestroyed, its information is stored in the memory bank. Subsequently if thesame process happens; the body will identify and analyze the bacteria and brainwill take the correct action. This is the procedure which happens when abacteria or fungi comes into all over the human body also the same process whichshows through the short animation clip.
