Complement is part of the innate immune system (one you are born with). It consists of small protein molecules that circulate in the blood stream.
Complement has three pathways, The classic pathway; The alternative pathway; and the lectin pathway.
In the classical pathway, complement is activated by triggers such as the binding of an antigen to an antibody. In the alternative pathway, Complement is part of the natural immune system and complement assist in the opsonization, or the marking of an antigen to be destroyed by a phagocyte. This like the antigen has been marked with black marker so that a killer cell (phagocyte-cell eater) can find it to eat it. Finally the lectin pathway, which is similar to the classical pathway in terms of structure but this pathway starts with lectin or ficolin binding to sugars. After activation complement can trigger any number of events such as opsonization, chemotaxis, inflammation, and lysis (breaking) of cells.

What plasma proteins are complement proteins?
Complement proteins are a series of immune proteins that carry out complement cascade reactions. These proteins are helping the immune system to lean up from the cells. complement proteins are not antibodies.
What is a inactive protein?
Complement proteins
What are compliment proteins?
Complement proteins are a group of proteins in the immune system that work together to enhance the body's ability to fight infections. They can help to attract immune cells to the site of infection, stimulate inflammation, and destroy pathogens by forming membrane attack complexes. Complement proteins play a critical role in the innate immune response.
How many plasma contains special complement proteins that form complement system?
11
What are complement deficiencies?
Complement deficiencies are a group of disorders in which there is a reduced level of specific proteins, complement, involved in proper immune functioning.
What are the components of the complement and kinin systems?
Plasma proteins
The group of proteins that normally circulate in the blood in an inactive form and are activated by contact with nonspecific antigens such as foreign blood cells or bacteria?
These proteins are part of the complement system, which forms a crucial part of the immune response. Once activated, the complement proteins can lead to the destruction of pathogens through processes such as opsonization, inflammation, and cell lysis.
What is The binding of complement proteins to certain sugars or proteins on a foreign Cell's surface?
Opsonization is the process where complement proteins bind to sugars or proteins on a foreign cell's surface, which marks the cell for destruction by phagocytic cells like macrophages and neutrophils. This process enhances the immune response against the foreign cell, helping to eliminate it from the body.
What is complement how does it cause bacterial lysis what are some othere roles of complement?
Complement is a group of proteins in the blood that help the immune system clear pathogens like bacteria. When complement proteins attach to a bacterial cell, they can form a membrane attack complex that creates pores in the bacterial cell membrane, leading to lysis. Other roles of complement include promoting inflammation, enhancing phagocytosis, and modulating the adaptive immune response.
What are complement proteins in blood stream of humans?

Which activity is parts of the inflammatory response?
complement proteins signaling phagocytes.
Which term describes a complex series of proteins that circulates in normal serum?
complement
