What is vaccination and how does it work?
In a vaccination you will receive a version of the pathogen (disease) that can not make you sick because it is inactive or significantly weakened. It will be introduced into your body with an injection or sometimes using oral or nasal formulations. Your immune system will then produce antibodies, which will kill or deactivate the introduced pathogen. Therefore, if an active/live pathogen would enter your body later, your immune system would be quickly able to produce more of the same type of antibodies, as they will recognizethe organism that caused the infection and know what antibodies will work on it. Boosters then might be used over the years to essentially remind the immune system how to defend your body against the pathogen.
Which of the following is the correct sequence of events in phagocytosis?
chemotaxis, adherence, ingestion, digestion, killing
Why is the immune system an obstacle to organ transplantation?
The body triggers an immune response because it detects a foreign object in the body. It is the same concept of a splinter. The body detects it and tried to push it out because it knows it isn't supposed to be there. your brain isn't trained to know that an organ transplant is to help the body out so it just sees it as an invader
Can normal flora become opportunistic pathogens?
Yes, normal microbial flora can become virulent or pathogenic if the conditions are right. On outside of body normal flora is harmless, if it was to be ingested it would take the opportunity to do as much damage as possible.
How does gluten cause inflammation?
Gluten is the protein. You get the same partially digested in your stomach. The polypeptides formed in this process go to your intestine. Three polypeptide sequences out of these are notorious. They probably form the antigen antibody complex with the proteins that are present in the brush border of your intestinal villi. This triggers the cellular response in which the lymphocytes migrate to the site. Not to eat the gluten protein is the only remedy for this problem at present. That is not the end of the world, if you can not eat few grains like wheat.
Do all pathogens need oxygen to grow?
no, not all pathogens need oxygen to grow. pathogens that grow without oxygen can occur in cooked rice, untreated garlic and oil mixtures, and temperature-abused baked potatoes.
What does the bone do in the immune system?
Your blood is used all around your body, it helps all of your organs function. The blood circles the brain and helps it function without it you'd be a mindless vegetable. Blood circulates around the body helping you and your entire body to function.
you shouldn't eat blood unless you are a vampire
What are proteins that activate the immune system and fight viruses?
They are called antibodies. Another term is immunoglobulins.
blood type O
What are components of the first line of defense?
The body's first line of defense against pathogens uses mostly physical and chemical barriers such as sweat, skin, tears, mucus, stomach acid, and so on. Our skin and other membranes which line the body passages are fairly effective in keeping most pathogens out of the body. Mucus can trap pathogens, which are then washed away or destroyed by chemicals. Tears, sweat, and saliva all contain chemicals to destroy pathogens to some extent.
There's multiple ways to organize the body's defenses. One way splits them into two parts: specific and nonspecific. Specific, also known as adaptive, is the last line of defense. This describes anything that targets the specific antigen, and not foreign substances in general. Specific includes lymphocytes, their antibodies, and the rather complex system that allows your body to become immune to certain invaders.
The non-specific, or innate, immune system is the first line. This includes the first line of defense as described in the first paragraph, but also includes non-specific cells such as macrophages and neutrophils, which will eat and destroy just about anything it encounters that isn't a part of your body. Also included are the complement system, inflammatory response and interferons, which are left for another question.
How are stomach acid and mucous as a defense against pathogen?
Stomach acid is a chemical barrier against pathogens. The low pH of the acid creates an environment in which pathogens are unable to survive and will often kill them.
Mucous is a physical barrier against pathogens. It acts to trap pathogens to prevent them from entering the body any farther.
What is a terrible viral disease that has been eradicated?
i really need the answer to that to. can someone with the answer please help or post a link to the answer :) thanks
What foreign substance elicits an immune response?
Any sort of "foreign" substance can, and most often will, elicit an immune response under certain curcumstances--provided the immune system is healthy. This would include bacteria, viruses and fungi.
Related: An unhealthy, or compromised immune system can act in all sorts of undesirable ways, ranging from low response to threat or injury to actually creating antibodies to attack its own system or other organs and tissue.
How does HIV weaken the immune system?
Alcohol, drugs, smoking, poor diet, emotional stress. over training, UV and radiation, chemical exposure, excess fat, inadequate protein, calorie, vitamin, mineral or water intake In addition, the biological state of aging counteracts immune function, particularly after age of 40.
How does the immune response to viruses differ from the immune response to bacteria?
It happens as our body do not have anti-bodies [ means the copy of the virus to make a trap for it ], but in bacterial it is done just by destroying as the bacteria do not conquer a tissue or a cell to make their army.
Antibodies stick to any viruses or infections. They don't attack, but they are like homing devices. They track the diseases so white blood cells (the attackers) know where the diseases are.
What acts as a barrier to keep foreign organisms and viruses out of your body?
THere are many barriers to prevent foreign organisms and viruses from entering your body. These include the skin, the mucous membranes of the respiratory system, the stomach acid, the enzymes in your tears, and the immune system.
Which one of the following is not a direct route of entry for Bloodborne Pathogens?
is NOT a likely route of entry for a bloodborne pathogen
Enhances phagocytes by coating a microbe. Opsonization promotes attachment of a phagocyte to a microbe.
