What defense target specific pathogens?
Lymphocytes
The body's most specific defense mechanism is?
The body's most specific defense mechanism is the immune system, which is responsible for recognizing and destroying specific pathogens and foreign substances. This is achieved through the production of antibodies that target individual pathogens, providing a specific and targeted response to threats.
The bodys most specific defense mechanism is the what?
The body's most specific defense mechanism is the adaptive immune system, which includes T cells and B cells. These cells can recognize and target specific pathogens based on their unique antigens, providing a tailored response to each invader.
What are the first 3 lines of defense?
The first line of defense is physical barriers like skin and mucous membranes, which prevent pathogens from entering the body. The second line of defense includes immune cells like neutrophils and macrophages, which attack pathogens that breach the first line. The third line of defense is the adaptive immune response, involving T and B cells that target specific pathogens and create immunological memory.
What is the difference between innate and adaptive defenses?
Innate defenses are the body's first line of defense against pathogens and are non-specific, meaning they target any foreign invader. Adaptive defenses are more specific and target particular pathogens, developing over time as the body is exposed to different threats. Innate defenses are always present and ready to act, while adaptive defenses take time to develop but provide long-lasting immunity.
Are non specific defence mechanisms more effective than specific defense mechanisms if so why?
Non specific defense mechanisms are more effective because they work against all bacteria and viruses. Examples are skin or tears. Specific defense mechanisms like antibodies work against one type of bacteria or virus. They're needed if a pathogen gets past the nonspecific defense mechanisms.
Why are antibodies important for the immune system's defense against pathogens?
Antibodies are important for the immune system's defense against pathogens because they specifically target and neutralize harmful invaders like bacteria and viruses, helping the body to fight off infections and stay healthy.
What is the third line of defense called?
The third line of defence against pathogens is called the Specific Immune Responce
How many line of defenses does the body have?
The body has three lines of defense against pathogens: the first line is physical barriers like skin and mucous membranes, the second line is non-specific immune responses like inflammation and phagocytosis by white blood cells, and the third line is the adaptive immune response involving specialized cells and proteins to target specific pathogens.
What cells are involved in specific defense?
Cells involved in specific defense include B and T lymphocytes. B cells produce antibodies that can recognize specific pathogens, while T cells can directly kill infected cells or coordinate immune responses. These cells are crucial for mounting a targeted and effective immune response against pathogens.
What is bodies second line of defense against pathogens?
the body's second line of defense against pathogens is the B cells.
How are B-cells involved in your specific defence?
B-cells produces antibodies that target specific pathogens so t-cells can then recognize it and consume it.
