True or false Vaccination triggers an immune response against the pathogen by simulating an infection?
True
True or false Anaphylactic shock is a hypersensitivity reaction that is a result of an inappropriately strong response of the immune system?
Yes.
True or false Fever is not a sign of infection.?
False. Fever is often a sign of infection, as it is the body's natural response to fight off pathogens such as bacteria and viruses. While there are other causes of fever, including inflammatory conditions and certain medications, it is commonly associated with infections.
Fever does not indicate infection. true or false?
false
The process of phagocytosis is an integral part of both specific and nonspecific immune defense activities?
Phagocytosis is a process where immune cells engulf and digest foreign particles, such as bacteria or viruses, to eliminate them from the body. It is a part of the nonspecific immune response, carried out primarily by macrophages and neutrophils. In the context of specific immunity, phagocytosis plays a role in presenting antigens to lymphocytes to initiate a more targeted immune response.
Is this true or false Allergies or hypersensitivities are normal immune responses?
They're abnormal immune responses - by definition, an allergy is an inappropriate response to a foreign substance. After all, it's not known as an 'allergy' when people's immune systems attack harmful pathogens, despite the body mounting somewhat similar immune responses.
A false negative result for valley fever?
There can be false-negative test for almost any disease including Valley fever.
The body's immune system attacks all micro-organism?
This statement is not accurate. The immune system is designed to distinguish between the body's own cells and foreign invaders, such as microorganisms. It targets and attacks only those that are recognized as harmful, while leaving healthy cells untouched.
False or true Immune surveillance by natural killer cells is one of the bodys most potent defenses against cancer?
True. Natural killer cells play a crucial role in immune surveillance by recognizing and eliminating cancerous cells, making them one of the body's important defenses against cancer. They can directly kill cancer cells and also produce cytokines to enhance the immune response against cancer.
When a variety of agencies are involved in a response the ics is superseded by the national response framework true or false?
False
Fever does not indicate infection.?
false
Basophils increase in number when parasitic invasion occurs?
Yes, basophils play a role in the immune response to parasitic infections. They can increase in number to help combat the infection by releasing chemicals such as histamine and heparin, which can trigger inflammation and defend against parasites. This response helps to activate other immune cells and aid in the body's defense against parasitic invaders.
