The complement system is a series of about 20 proteins that are involved in a cascade effect during an immune response. Complement is generally divided up into 3 pathways: classical, lectin, alternate. The classical pathway involves a complement protein binding to an antigen-antibody complex (and thus its role in adaptive immunity). Whereas in the alternate pathway, complement (C3) binds directly to the foreign cell( usaully bacteria). Thus its repsonse is non specific and therefore is also part of the innate imune system.

What immune system is activated if the innate immune system is unable to control the infection?
The adaptive immune system is activated if the innate immune system is unable to control the infection.
Are toll-like receptors considered part of the innate immune system or the adaptive immune system?
Toll-like receptors are part of the innate immune system.
Is basophil an Innate or Adaptive Immune system?
No, the first line of the immune system is the intact skin, mucous membranes and their secretions, normal microbiota all are physical barriers.
Is the innate immune system selective?
no
What is an adaptive immune system?
An adaptive immune system is a series of specialized, systemic cells and processes which remove or counter pathogenic growth.
What are the antibodies of the innate immune system?
The innate immunes system does not produce any antibodies. Cells of the innate immune system are macrophages, granulocytes (neutrophils, basophils, eusinophils), natural killer cells...
Is mucus part of the adaptive or innate immune system?
Mucous is an innate immunity, it is a powerful early defense mechanism and highly effective physical barriers against microorganisms. Mucous can be found in respiratory tract, gastrointestinal tract, and genitourinary tract.
Which system in the body does HIV damage?
Acquired Immune System or Adaptive immune System
Which structure is not a component of the adaptive immune system?
tissues
What is not a part of the innate immune defenses?
which of these is not apart of the body immune system
What is C3 convertase?
Humans have both an "innate" and an "adaptive" immune system. There are a number of proteins circulating in the blood as part of the complement system that belongs to the innate immune system (although the adaptive system can activate it as well). Normally, the complement proteins are inactive. When the immune system detects some threat, the complement system is triggered and the circulating proteins are chemically split into smaller components. C3 convertases are chemicals that cleave C3 complement into breakdown products in both the "classical" and the "alternative" pathways of the complement system.
Which cell of the immune system is absolutely required for an adaptive immune response?
T helper cells
