so I asked the right question, let me take a look at the link..Originally posted by Adrian
Just how this is accomplished has long been a source of debate among biologists and immunologists."
Immune cells are specialized cells in the body that play a crucial role in defending against foreign invaders, such as bacteria, viruses, and other pathogens. They are part of the immune system, which is responsible for fighting off infections and preventing illness.
Immune cells are able to move through cellular barriers, such as blood vessel walls, by using a process called diapedesis. During diapedesis, the immune cells are able to change their shape and squeeze through small openings in the cellular barriers, allowing them to reach the site of infection or injury.
The purpose of immune cells squeezing through cellular barriers is to reach the site of infection or injury quickly and effectively. This allows them to eliminate the foreign invaders and prevent the spread of infection, which helps to protect the body from illness and disease.
Once immune cells have successfully squeezed through cellular barriers, they continue to travel to the site of infection or injury. There, they can either directly attack and destroy the foreign invaders or signal other immune cells to join in the fight.
While immune cells are highly efficient at squeezing through cellular barriers, there are certain factors that can hinder their movement. These include inflammation, which can make the cellular barriers thicker and more difficult to pass through, and certain diseases or medications that can affect the immune system and its ability to fight infections.
