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.
Where do antigens, the substances that trigger an immune response in the body, originate from?
Antigens, which trigger the immune response in the body, originate from foreign substances like bacteria, viruses, and other pathogens, as well as from the body's own cells that have been altered or damaged.
How is invading bacteria detroyed?
The bacteria has tiny, oddly-shaped molecules on it's surface, which are different for every type of bacteria, these are called antigens. When a special type of white blood cell, called a lymphocyte, realises an invading bacteria is in the bloodstream, it starts to make tiny connectors called antibodies. These antibodies fit the antigens on the bacteria's surface, and join many bacteria together. Once lots of bacteria have been joined together, another type of white blood cell, called a phagocyte, engulfs them, and it will usually take a few days for all the bacteria to be destroyed.
React with antigens and inactivates them?
This describes the role of antibodies in the immune response. Antibodies bind to antigens, such as viruses or bacteria, and either mark them for destruction by other immune cells or neutralize their effects. This process helps the immune system to recognize and eliminate harmful invaders.
Antibodies work by attaching to the what making them useless?
Antibodies attach to antigens, which are foreign substances such as viruses or bacteria, to make them harmless by marking them for destruction by the immune system.
What is a group of proteins that normally circulate in the blood in an inactive form and activated by contact with nonspecific antigens such as foreign blood cells or bacteria is known as?
A group of proteins that circulates in the blood in an inactive form and is activated by contact with nonspecific antigens, such as foreign blood cells or bacteria, is known as the complement system. This system plays a crucial role in the immune response by helping to clear pathogens and promote inflammation. Once activated, complement proteins can enhance opsonization, facilitate phagocytosis, and contribute to the lysis of pathogens.
What prodrug is activated by colonic bacteria when given orally?
Balsalazide-azo-bonded prodrug, activated by bacteria in the colon

What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
Serological testing is based on the fact that antibodies react specifically with an anigen all bacteria have the same antigens or the human body makes antibodies against bacteria?
AnswerThe human body makes specific antibodies to specific antigens (ex. proteins on a bacterial membrane) that it encounters. Bacteria do not all have the same antigens.* antibodies react specifically with an antigen
Is skin specific or nonspecific?
Yes, the skin is the most important nonspecific defense. This is because your oil and sweat glands are acidic.
Do all bacteria have antigens if so what would happen if it entered your system?
yes they do
Can plasmids or bacteriophages be used in vaccines to fight bacteria?
Yes, plasmids can be used in DNA vaccines to fight bacteria by expressing antigens that trigger an immune response. Bacteriophages can also potentially be used in vaccines by delivering antigens or genes into host cells to stimulate an immune response against bacteria.
What best describes an example of a nonspecific internal response to harmful bacteria?
An example of a nonspecific internal response to harmful bacteria is inflammation. Inflammation is a general response triggered by the immune system to protect the body from foreign invaders. It involves increasing blood flow to the area, causing redness, swelling, and pain.
What is a foreign chemical that stimulates the production of antibodies?
An antigen is a foreign chemical that stimulates the production of antibodies by the immune system. Antigens can be bacteria, viruses, toxins, or other substances that are recognized as foreign by the body.
What is the use of genetically engineered bacteria?
The can produce antigens useful in making vaccines without the harmful parts of the original disease organism.
How many antigens are there in the human body?
There is no definite number of antigens in the human body as the immune system can recognize a wide range of foreign substances. Antigens can come from pathogens like bacteria and viruses, as well as from our own cells in cases of autoimmune diseases. The human body constantly encounters new antigens and can generate immune responses against them.
