This picture, published in Nature magazine, shows one of the immune cells in the human body, T cells(the green ones). T cells travel through the blood vessels, and when they reach the target point, they squeeze into the gaps in the blood vessel walls to examine the cells in the body.

At this very moment, hundreds of billions of immune cells like T cells in your body go around on their own, spontaneously, and examine each cell in the body.

Each one of these individual immune cells is a separate supergiant biological system.

Immune cells make contact with the cells as shown in the following figure, checking one cell after another, again and again, whether the nutritional status of the cells in our body is okay, whether there is something wrong, and whether there are no signs of pathogens, viruses, or cancer.

When an abnormality is detected, it informs the cell about the appropriate initial countermeasures, acts itself as an immune cell, or reports it to a higher-level system so that the body can take procedures to restore normality through an appropriate response.

The following figure is a mimetic diagram of the system that T cells and regular cells exchanging a biological signal.

It is a wonder that the current technology and comprehension of the science could make these pictures, however, it is it, no more. Human have only started to understand what mechanism manage such a biological system.
