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.
How does the immune system fight leptospirosis?
The immune system combats leptospirosis through both innate and adaptive responses. Initially, innate immune cells, such as macrophages and neutrophils, recognize and respond to the leptospiral bacteria, helping to contain the infection. Subsequently, the adaptive immune system activates, producing specific antibodies against the bacteria, which neutralize them and help eliminate the infection. Additionally, T cells play a critical role in orchestrating the immune response and clearing the infection from the body.
What are the two levels of defense that humans have against patghogens what do their names mean?
Humans have two levels of defense against pathogens: the innate immune system and the adaptive immune system. The innate immune system provides immediate, non-specific responses to a wide range of pathogens, acting as the body's first line of defense. In contrast, the adaptive immune system is specific and develops a targeted response to particular pathogens, including the formation of memory cells for long-term immunity. Together, these systems help protect the body from infections and diseases.
Is the innate immune system selective?
no
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...
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.
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
Which line of immune defense was broken in his immune system when infected?
When an individual is infected, the first line of immune defense, which includes physical barriers like the skin and mucous membranes, is often breached. This allows pathogens to enter the body, where they can interact with the second line of defense, including innate immune responses such as inflammation and phagocytosis. If these defenses are overwhelmed or compromised, the adaptive immune response may also be activated. Thus, the initial breach typically occurs at the level of the physical barriers.
