What else can I help you with?
What is the third line of defense called?
The third line of defence against pathogens is called the Specific Immune Responce
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.
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 is the level of defence against infection?
1) surface barriers include the skin and mucous membranes. Gastric Juice,: Concentrated hydrochloric acid (HCl) and proteases that destroy pathogens in the stomach 2) second line of defence: the non-specific defence mechanisms such as inflammation, fever, phagocytic leucocytes, anti-microbial proteins 3) third line of defence: specific defence: Antigen (Macrophages encounter a pathogen, they digest it and present the antigenic fragments on their surface to helper T lymphocytes) and Antibody (B lymphocytes )
Is skin an example of innate immunity or acquired immunity?
Skin is an example of innate immunity. It serves as a physical barrier that protects the body from pathogens and prevents their entry. Innate immunity is the body's first line of defense, providing immediate, non-specific responses to infections, unlike acquired immunity, which develops over time and targets specific pathogens.
What is the main function of the immun system?
The immune system plays an important role in the body's defence mechanisms. It destroys and eliminates the pathogens that invade our bodies.
How many targets did the Luftwaffe destroy in World War 2?
They didn't completely destroy targets, as Britain's defence system was strong, and helped us to win the Battle OF Britain. However, the main targets were Southeast England & the London area.
What body systems work together to protect the body from pathogens?
The immune system and the lymphatic system work together to protect the body from pathogens. The immune system recognizes and targets pathogens, while the lymphatic system helps circulate immune cells and remove pathogens from the body. Additionally, the skin and mucous membranes act as physical barriers to prevent pathogens from entering the body.
In Mexico are they killing American tourist?
As specific targets? No.
What types of pathogens are specific to the nose?
infleunzae virus
What defense target specific pathogens?
Lymphocytes
What do you test for when sampling for pathogens?
When sampling for pathogens, it's essential to test for specific microorganisms such as bacteria, viruses, and fungi that can cause disease. Common targets include pathogens like Salmonella, E. coli, Listeria, and various viruses depending on the source (e.g., food, water, or clinical samples). The testing process typically involves using culture methods, molecular techniques like PCR, or immunological assays to detect and quantify these pathogens effectively. Additionally, assessing the sample's environmental conditions and potential contamination sources is crucial for accurate results.
