yes
It would be their immune system.
The specific defense system is also known as the acquired immune system.
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.
The body is made up of a specific defense system and nonspecific defense system. The nonspecific defense system is made up of inflammation, fevers, etc. The immune system is part of the specific defense system. This is because the lysosomes in this system bind to specific antigens and have a certain role to carry out. Therefore, there aren't nonspecific defenses in the immune system.
yes
The immune system
The body's defense system is the immune system.
the immune system
Because the body does what it wants
An immune response is part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically toward that pathogen.
The innate immune system is the branch of the immune system that responds immediately to pathogens. It provides rapid but non-specific defense mechanisms, such as physical barriers and inflammatory responses, against a wide range of invaders.
No, the circulatory system is not the last line of defense against infection. The immune system plays the primary role in defending the body against infections. The circulatory system helps in distributing immune cells and antibodies throughout the body to fight off infections, but it is not the final line of defense.
