No, the first line of the immune system is the intact skin, mucous membranes and their secretions, normal microbiota all are physical barriers.
The adaptive immune system is activated if the innate immune system is unable to control the infection.
Toll-like receptors are part of the innate immune system.
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.
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.
no
The innate immunes system does not produce any antibodies. Cells of the innate immune system are macrophages, granulocytes (neutrophils, basophils, eusinophils), natural killer cells...
An adaptive immune system is a series of specialized, systemic cells and processes which remove or counter pathogenic growth.
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.
Acquired Immune System or Adaptive immune System

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 of these is not apart of the body immune system
