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.
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 )
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
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
How is specific defense different from nonspecific defense?
Specific defense, also known as adaptive immunity, targets specific pathogens and involves a tailored response, including the activation of lymphocytes (T and B cells) and the production of antibodies. In contrast, nonspecific defense, or innate immunity, provides a generalized response to a wide range of pathogens through physical barriers (like skin), inflammatory responses, and immune cells that act quickly but without specificity. Essentially, specific defenses are more specialized and take longer to activate, while nonspecific defenses act immediately and broadly.
