If a pathogen crosses the second line of defense, which includes innate immune responses like inflammation and phagocytosis, the body activates the adaptive immune system. This involves the activation of lymphocytes, such as T cells and B cells, which specifically target and eliminate the pathogen. The adaptive response also generates memory cells, providing long-lasting immunity against future infections by the same pathogen. If the adaptive immune response fails, the infection can progress and potentially lead to illness.
What else can I help you with?
What is the first line of defense of a pathogen?
The first line of defense against a pathogen would be barriers. Ex. The skin, Breathing Passages, and The Mouth and stomach.
Is inflammation a type of non specific defense specific defense acquired defense or all of the above?
It is a non-specific Immune response as it does not change based on interaction with a pathogen and will activate regardless whether the pathogen in question has been encountered previously. Commonly referred to as being part of the "Second Line of Defence".
What is the last line of defense against an extracellular pathogen?
antibody production by plasma cells
What is first line of defense and what is second line of defense?
skin and mucous membranes first line of defense second line-leukocytes and macrophages, inflammation and fever third is immune system
When does the bodys secound line of defense come into play?
The body's second line of defense comes into play when pathogens breach the first line of defense, which includes physical barriers like skin and mucous membranes. This response is part of the innate immune system and involves various mechanisms such as inflammation, the activation of phagocytes, and the release of antimicrobial substances. These actions help to contain and eliminate the invading pathogens. Additionally, the second line of defense is non-specific, meaning it responds the same way regardless of the type of pathogen encountered.
What is bodies second line of defense against pathogens?
the body's second line of defense against pathogens is the B cells.
Second line of defense against microorganisms?
The Second Line of defense is mainly called the Inflammatory Response. Some may say the immune response is the second layer too. The Second Line of Defense also includes leukocytes such as macrophages.
Which of the following best describes the function of the IAMMUNE SYSTEM?
Prevents the invasion of of pathogen into the body and acts as the first and second line of defence Agianst pathogens
What level of prevention is a vaccine?
there are actually three categories of defenses in the body, namely: first line of defense, second line of defense and the third line of defense.first line of defense is our skin. the vaccine you're talking about falls under the second line of defense because it involves the immune system wherein these vaccines were introduced into the body,nonetheless, the cells on our body creates/secretes chemicals that serve as defense mechanism; and the third line of defense is the use of medications or chemicals prescribed by the doctors.
How does the third line of defense come into play?
when the first and the second lines of defense have already been overcome.
Are phagocytes part of the second line of defense against microorganisms?
Yes, phagocytes are part of the second line of defense in the immune system. They help to engulf and destroy pathogens that have breached the first line of defense such as the skin and mucous membranes. Examples of phagocytes include macrophages and neutrophils.
Is gastric juice considered to be a second line of defense?
Gastric juice is not typically classified as a second line of defense; rather, it is part of the body's first line of defense against pathogens. It contains hydrochloric acid and digestive enzymes that help to kill harmful microorganisms ingested with food. This acidic environment plays a crucial role in preventing infections in the gastrointestinal tract. The second line of defense generally refers to immune responses, such as inflammation and the action of white blood cells, which respond to pathogens that bypass the first line of defense.
