killer cells
White blood cells are the good cells in the body. Yes you do need red and white blood cells, but the white ones fight off diseases or pathogens. If white blood cells cannot do this then the immune system fails. The pathogens depending on their severity, could hurt the body very much. Doctors do different tests and procedures to help this not happen. White blood cells are needed to protect the body from pathogens. When they cannot stop the invading pathogens, a person will most likely get sick. on NovaNet I'm pretty sure that the answer is the person will die:))
the disease invades them and our body
White blood cells can attack microbes within the bloodstream, tissues, and lymphatic system. They can also migrate to infected tissues and organs to combat invading pathogens.
Antibodies are released by B-lymphocytes (one of thekinds of white blood cells)
A macrophage is the type of white blood cell that surrounds and kills invading cells.
Most of the white blood cells are phagocytic in function. But white blood cells like lymphocytes produce antibodies and are responsible for the immune response of the body.
The main function of white blood cells (also commonly referred to as leucocytes) is to defend against foreign invading pathogens that may enter the body. They do this as they are phagocytes, in that they engulf pathogens and destroy them. Therefore, the function of a white blood cell is to defend the body against infection.
White blood cells can get to the site of infection through a process called chemotaxis, where they are attracted to the area by chemical signals released by the damaged tissues or invading pathogens. Once they reach the infection site, white blood cells can engulf and destroy the invading microorganisms to help fight the infection.
White blood cells, also known as leukocytes, are the cells that play a crucial role in the body's defense against invading microbes. They work by identifying and attacking foreign invaders such as bacteria, viruses, and other pathogens to help prevent infections.
Yes, white blood cells can ingest pathogens through a process called phagocytosis. This allows white blood cells to destroy and eliminate harmful pathogens, such as bacteria and viruses, from the body.
