How does resident normal flora protect the body against pathogens?
Resident normal flora compete with pathogens for nutrients and space, thereby preventing pathogens from colonizing and causing infections. Additionally, normal flora can produce substances that inhibit the growth of pathogens or modulate the immune response to promote defense against invading pathogenic organisms.
Which of these is the human body's first line of defense against invading pathogens such as bacteria and viruses?
skin and mucous membranes
What is immune response?
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.
What disease does immune globulin treat?
There are many types of immunoglobulin within the body. They are part of the immune response which the body activates when a pathogen/bacteria/virus enters the body. The body responds by initiating an innate response in which pathogens are phagocytosed (literally eating) by defense cells. The immunoglobulins help recognise these pathogens and tell the body that they are a foreign material so they can be destroyed.
What body's continuing immune response and defense against pathogens it has seen before is known?
Active immunity
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 activity does cell 1 undertake to contribute to the body's defense against injury and infection?
Cell 1 may be a white blood cell responsible for fighting off pathogens such as bacteria and viruses. These cells play a crucial role in the immune response by detecting and destroying invading pathogens to protect the body against injury and infection.
What organ is your first line of defense against pathogens?
The integumentary system (skin) and mucous membranes are the first line of defense. They provide a physical barrier against invasion of pathogens. Any break in this physical barrier, such as a cut, makes it easier for pathogens to enter your body.
What type of white blood cells kill pathogens by engulfing them?
Phagocyte
How does interleukin 1 amplify the body respond to an invasion?
Interleukin-1 (IL-1) is a key pro-inflammatory cytokine that plays a crucial role in amplifying the immune response to infections and tissue damage. It is produced by activated macrophages and other immune cells in response to pathogens or injury. IL-1 enhances the recruitment and activation of additional immune cells, such as neutrophils and T cells, while also promoting the production of other inflammatory mediators. This amplification helps to increase the overall inflammatory response, facilitating a more effective defense against invading pathogens.
What is bodies second line of defense against pathogens?
the body's second line of defense against pathogens is the B cells.
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.
