Infections are fought by white blood cells. These cells include: + T-Cells (T lymphocytes) -- Killer T-Cells -> Kill infected cells in your body -- Regulatory T-Cells -> Help to modulate other infection-fighting cells. -- A few other types. + B-Cells (B lymphocytes)-> When activated produce antibodies that will bind to and either inactivate or destroy foreign substances. + Granulocytes: -- Neutrophils -> Kill invading microbes either by ingesting them or releasing specific proteins. -- Eosinophils ->Kill invading parasites (like parasitic worms). Also important in infection related inflammation. -- Basophils -> Preventing blood clotting and increase blood flow to sites of infection. + Monocytes -> Ingest and destroy foreign substances. + Also important in fighting infections are a range of antigen presenting cells. Antigen presenting cells either ingest a foreign substance or become infected. In doing so, they are able to present some of the proteins made by the foreign microbe or virus on their surface for lymphocytes to interact with. Lymphocyte interaction with antigen presenting cells is the first step in lymphocyte activation. These cells typically include dendritic cells, macrophages, B-cells, and some epithelial cells, but a variety of other cell types can play a role.

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.
Which cells are able to protect the body by engulfing foreign cells or protecting antibodies?
Phagocytes
Which cells are able to protect the body by engulfing foreign cells or producing anitibodies?
White blood cells
How does producing antibodies protect us from disease?
Producing antibodies is a part of the immune response that helps to recognize and neutralize specific pathogens, such as bacteria or viruses. Antibodies bind to the foreign substances, marking them for destruction by immune cells, and prevent them from causing infection. This immune response helps to protect the body from getting sick and can also provide immunity against future infections.
What is the function of the plasma cell?
produce antibodies Plasma cells are antibody-manufacturing cells derived from B lymphocytes, following their activation by an antigen. They are responsible for humoral immunity - immunity conferred by antibodies present in the blood plasma. Plasma cells are capable of synthesising and secreting antibodies at a rate of 2000 molecules per second. Each cell will only synthesise and secrete one type of antibody. This antibody will bind specifically to the antigen that initially activated the precursor B lymphocyte. Plasma cells will synthesise and secrete antibody molecules over their short life span of 4 to 5 days. The secreted antibodies circulate in the blood or lymph and bind to their complementary antigen, thus marking them for destruction by other mechanisms.
What were the first types of cells able to make their own food?
The first types of cells able to make their own food were likely primitive prokaryotic cells, specifically cyanobacteria. These cells were able to perform photosynthesis, converting sunlight into energy through the use of chlorophyll and producing their own food through this process.
Why would your body stop producing anti bodies?
It makes antibodies all the time. If it stopped, you would not be able to fight of infections and would die. People who are infected with HIV and have AIDS, have this problem.
How antigens are affected by antibodies?
They both are able to reproduce by earanal sex and also they are both able to fight of disease with swordskies, but unfortunately only antigens are found in fabrics such as carpets and bed spreads...
Can an antibody penetrate the host cell to bind intracellular antigen?
The majority of antibodies bind secreted or membrane bound antigens and do not penetrate cells. Antibodies can be taken up into cells via endocytosis. However, a subset of autoantibodies isolated from autoimmune diseases in humans and mouse models are able to penetrate cells and bind to their antigen in the cytoplasm or nucleus (e.g. anti-DNA autoantibodies).
What effect would antibodies have on a virus that causes the flu?
Antibodies can attach to and render a virus unable to attach to your cells to infect them. If you get a preventive vaccination, your antibodies will get to work on this project much sooner and you may feel no symptoms at all. More: Antibodies are specific to each particular virus or other pathogen, and play a key role in the immune response to invading virus infections. The antibodies are created to be the perfect shape to block the virus from being able to attach to the cells. If unable to attach to the cell, the virus can not reproduce. See related questions below for more information about the immune response to viral infections.
What will happen if the white bloods cells are not able to stop the invading pathogens?
then antibodies are produced to help If the blood cell did not able stop the pathogen then it will result in disease or toxicity which will make the person ill and may be it can result in immunity for feature
What are the lymph nodes made out of?
lymph nodes are made out of lymphoid tissuethat is able to receive the lymph and return cleaned lymph back into the circulation. Generally the cell types found in the lymph nodes are antigen-presenting cells (specifically dendritic cells), T cells (both helper CD4 T cells and killer CD8 T cells) and B cells (which produce antibodies).
