Foreign cells are not inherently bad; their effects depend on the context. In the immune system, foreign cells, such as pathogens, can trigger an immune response, which is necessary for protecting the body. However, foreign cells can also be beneficial, such as those from donor organs in transplants or certain therapies. The key lies in how the body recognizes and responds to these foreign cells.
What else can I help you with?
What is Tc cells?
Tc cells are cytotoxic cells that are "effetors" of cellular immunity that carry out the attack on a foreign cells in other words Tc cells kill cells that have been infected by a foreign substance
What kind of cells activate the immune system when foreign substances appear?
Cells called antigen-presenting cells, such as dendritic cells and macrophages, play a key role in activating the immune system when foreign substances appear. These cells identify and capture foreign antigens, present them to T cells, and help initiate an immune response.
Which cells are able to protect the body by engulfing foreign cells or producing antibodies?
Immune cells such as macrophages and neutrophils are able to engulf foreign cells through a process called phagocytosis. B cells and T cells are specialized in producing antibodies to target and neutralize foreign invaders.
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
These specialized cells are called immune cells, particularly T cells and B cells. They play a crucial role in the body's immune response by identifying and responding to foreign antigens to eliminate them and protect the body from infections.
What are bad cells?
"Bad cells" could refer to cancer cells, which are abnormal cells that divide uncontrollably and can invade surrounding tissues. These cells can form tumors and impact the functioning of normal cells in the body.
Does phagocytosis mean bad breath?
No. I think you're referring to halitosis. Phagocytosis is the process where cells in your body engulf dead or foreign bodies.

What combines with antibodies to dissolve foreign cells?
complement system cells
What are cells that eat up foreign cells?
Cells that eat up foreign cells are known as phagocytes, such as macrophages and neutrophils. These cells play a key role in the immune system by engulfing and digesting foreign particles, including pathogens and other debris.
Specialized cells that attack foreign substances upon recognizing the foreign surface antigens are called?
These specialized cells are called immune cells, particularly T cells and B cells. They play a crucial role in the body's immune response by identifying and responding to foreign antigens to eliminate them and protect the body from infections.
What are the cells that combine with foreign antigens and present them to t cells called?
Those cells are called antigen-presenting cells (APCs). They include dendritic cells, macrophages, and B cells. Their role is to ingest foreign antigens, process them, and present them to T cells to initiate an immune response.
Which cells are able to protect the body by engulfing foreign cells or producing anitibodies?
White blood cells
What are bad cells?
"Bad cells" could refer to cancer cells, which are abnormal cells that divide uncontrollably and can invade surrounding tissues. These cells can form tumors and impact the functioning of normal cells in the body.
What protein in b cells produce that attack foreign cells are?
The protein produced by B cells that attacks foreign cells is called antibodies or immunoglobulins. Antibodies specifically target and neutralize pathogens like bacteria and viruses.
Why is it bad to loose white blood cells?
White blood cells are your defence against foreign microorganisms. If you have a shortage of white blood cells, you can easily be affected by what other people are not. For instance if somebody passed on their germs to you, you could be affected by a cold or flu that they weren't affected by because their white blood cells were fighting it off
