Antibodies are produced in a White blood cell called a plasma cell. The antibody is made for a specific type of pathogen which it recognises by it's antigen. The antibody will link on to the pathogen and either destroy it or hold on to it until another White blood cell will come and ingest (eat) it.
What else can I help you with?
What marks foreign invaders and attracts phagocytes?
Foreign invaders are marked by antigens on their surface, which attracts phagocytes like macrophages and neutrophils. These phagocytes recognize the antigens as non-self and engulf the invaders through a process called phagocytosis, helping to remove them from the body.
If foreign substances pass the body's first line of defense and into the bloodstream.what happens?
The immune system's second line of defense is activated. This includes white blood cells attacking the foreign substances, inflammation to isolate the invaders, and antibodies produced to help eliminate them. The immune response aims to neutralize and remove the threat from the bloodstream to protect the body from harm.
What is one of the main roles of the lymphatic system?
The job of the lymphatic system is to detect, filter and remove bacteria and other foreign invaders while maintaining fluid balance.
What washes foreign substance from the eye?
Tears wash foreign substances from the eye. They are produced by the lacrimal glands and contain enzymes and antibodies that help remove debris and protect against infection. Additionally, blinking helps spread tears evenly across the surface of the eye, aiding in the removal of irritants.
What effect does the vaccine have on the body?
A vaccine contains the pathogen ( a foreign body which causes diseases/illnesses) which the virus is designed to provide protection for ie: a flu vaccine will contain a flu virus, measles has the measles virus etc... - but they have been treated so they are in effect dead and so will cause no symptoms, your body can only recognise a pathogen, it does not know that it is dead and can not harm you,so your body produces antibodies ( cells that fight off and remove pathogens from the body) to fight this vaccine, the antibodies remain in the body forever (unless you have an autoimmune/immunodeficiency illness) so when you come into contact with say the flu your body already has the antibodies and you don't get sick because your body removes the pathogen before it gets chance to take hold.
Describe what can happen to an antigen when it enter the body?
Antibodies do not "get in to your body" from an external source. When your body's immune system (your bodies way of defending and protecting itself against pathogens and disease) thinks that there is something in your body that might hurt you (a virus or bacteria) it forms antibodies to attack the "foreign" object. So, Antibodies are actually formed by your own body and not introduced from outside of it. Hope that helps!
What is the function of tracheal mucosa?
The tracheal mucosa produces mucus to trap and remove foreign particles, such as dust and pathogens, from the airways. Additionally, the mucosa helps to humidify and warm the air as it moves through the respiratory tract.
How did Britain react to Argentina invading the Falkland islands?
They sent a naval task force to remove the invaders.
The organ that filters blood is the?
The spleen acts as a filter for your blood, cleansing it of bacteria, viruses and other debris. When blood flows through your spleen, white blood cells attack and remove any foreign invaders. This keeps your blood clean and helps protect you against infection.
How does a body recognize a virus?
Confusing question. Essentially, one way your body recognizes viruses by the antibodies it left behind the last time you were infected. Another is the sheer presence of something "different."Antibodies (immunoglobulin) are Y-shaped proteins that are produced by plasma cells, and which have millions of variable. At each tip of the "Y" is an antigen binding site (paratope), in essence a lock. When your body comes into contact with a foreign pathogen or substance, the antibodies (epitopes) of the invader trigger the immune system to produce antibodies. the antibodies with paratopes that correspond to the epitopes of the invader are attached, and the invader is neutralized or killed.The problem occurs when your body does notrecognize a virus or some other invader. At these times your body has no or reduced defense against the pathogen, and in serious cases (bubonic and pneumonic plagues, dengue and hemorrhagic fevers, ebola, haunta, super flues such as H1N1 or Swine Flu, and SARS) the immune system cannot fight it and becomes overrun.Any invasion of the body by a foreign substance or pathogen automatically triggers an immune response. In very simple terms, the body produces what are called cytokines. Cytokine are cell-signalling proteins, peptides, and glycoproteins and are molecules that message the presence of any substance or pathogen they see as an invader. Cytokines are one of the first steps in the innate immune system, and can trigger the production of other cells, biochemicals, hormones, and other immunological responses that attack and work to remove the threat. How they mark and target invaders and initiate production of the various types of immunological response is still not very well known.
Protein that helps with immune system defense?
Proteins help form immunoglobulins, or antibodies, to fight infection ( 25 , 26 ). Antibodies are proteins in your blood that help protect your body from harmful invaders like bacteria and viruses. When these foreign invaders enter your cells, your body produces antibodies that tag them for elimination ( 27 ).
What is plasmapheresis used for?
is used to remove antibodies from the bloodstream, thereby preventing them from attacking their targets. It does not directly affect the immune system's ability to make more antibodies, and therefore may only offer temporary benefit.
