Disulfide bonds hold together the chains of antibodies. These bonds form between cysteine residues in the antibody's structure.
The bone marrow, the lymph nodes, the spleen, and the thymus are the organs that are part of the immune system, all of which work together to produce the different types of white blood cells which keep you alive.
Macrophages ingest microorganisms and cellular debris. Lymphocytes monitor the lymphatic stream for the presence of antigens and mount an immune response. Because there are fewer efferent vessels draining the node than afferent vessels that feed it, the flow of lymph through the node stagnates somewhat, allowing time for the lymphocytes and macrophages to work.
The bacteria has tiny, oddly-shaped molecules on it's surface, which are different for every type of bacteria, these are called antigens. When a special type of white blood cell, called a lymphocyte, realises an invading bacteria is in the bloodstream, it starts to make tiny connectors called antibodies. These antibodies fit the antigens on the bacteria's surface, and join many bacteria together. Once lots of bacteria have been joined together, another type of white blood cell, called a phagocyte, engulfs them, and it will usually take a few days for all the bacteria to be destroyed.
Both macrophages and dendritic cells are formed from the same precursor cell, the monocytes. However, the two cells serve different functions during an infection. Macrophages remain in the area of the infection and phagocytosis (engulf) foreign invaders and dead cells. Dendritic cells leave the infected tissue and travel to local lymph tissue in order to alert the adaptive immune system.

so they can eat them at once, and stop them from spreading i mean antibodies eat the virus up....
When blood is mixed with matching antibodies, the red blood cells will agglutinate, or clump together. This reaction occurs because the antibodies bind to specific antigens on the surface of the red blood cells, leading to the formation of visible clumps. This process is crucial in blood typing and transfusion compatibility tests to prevent adverse reactions during blood transfusions.
If anti-B antibodies (from someone who is blood type A or AB) are mixed with group B red cells, agglutination or clumping of red cells will occur due to a reaction between the antibodies and the B antigen on the red cells. This can lead to transfusion reactions if incompatible blood is transfused, causing harm to the recipient.
Macrophages, granulocytes, and lymphocytes are key components of the immune system that work together to locate, recognize, and eliminate pathogens. Macrophages and granulocytes use pattern recognition receptors to identify common features on pathogens, such as lipopolysaccharides or peptidoglycan, facilitating their engulfment and destruction through phagocytosis. Lymphocytes, particularly T cells and B cells, recognize specific antigens presented by infected cells or pathogens, leading to targeted immune responses: T cells can directly kill infected cells, while B cells produce antibodies that neutralize pathogens or mark them for destruction. Together, these immune cells coordinate a robust response to eliminate infections.
The cells capable of fighting bacterial infection in the body are white blood cells, specifically neutrophils and macrophages. These cells work together to engulf and destroy bacteria using mechanisms such as phagocytosis and releasing antimicrobial substances.
Type B antibodies react to type B antigens by begining to clump together, and the clumps may block blood vessels.
antibodies are proteins that stick to the invading microorganisms the antibodies lock onto the antigen and force the bacteria or viruses to clump together.
An antibody is a Y shaped proteins that are cruical to the specific immune response and are released by lymphocytes. The top "arms" of the Y have sites that recognise and bind specfic counterparts, other proteins called antigens, on cells that are not SELF (cells that are part of the organism producing the antibodies). Each of the arms on one antibody recognises the same antigen as it partner arm and so each antibody binds two atingens. This mean that potentially two cells can be bound together and this is the primary function of antibodies, to bind masses of cells together making them inefctive at damaging SELF cells and as a mass they are phagocytosed by macrophages. Antibodies are also present on T-lymphocytes which use them to recognise non-self cell and directly destroy them.

The type of chemical reaction that connects polymers together is dehydration synthesis.
