Can antigens trigger a response of the immune system?
Anti gens bind to viruses/bacteria that 'fit' them, clumping together and allowing phagocytosis. They tend to be specific to one strain hence why we cannot vaccinate against a virus that mutates frequently or has many strains.
What structures provide physical or chemical barriers against microbial invasion?
The skin and mucous membranes provide living things with physical and chemical barriers against invasion of microbes. These membranes are part of the immune system.
If your blood clumped with both anti-a and anti-b sera your ABO blood type would be what?
it would be type AB.
What is the first antibody made in response to an antigen?
IgM is the antibody first secreted during primary response

Leukocyte in small amountwhat does that mean in a urinalysis test?
One to five leukocytes per high power field on the microscope is considered normal, However, one should look at the whole field and evaluate this as a whole picture. If also many bacteria are present as well and/or many red blood cells, then a pathologic picture may be present (ie a condition such as an infection or other kidney disease). If your urine is absent of other abnormal findings, and a small amount of Leukos are seen, I would not worry about it.
What defends the body against toxins and pathogens?
.Immune system-complex set of defenses to protect the body from pathogens in by students on the
B.First-line defenses-resist pathogens
1. Unbroken skin is a barrier that prevents many pathogens from entering the body.
2. The respiratory system traps pathogens with cilia and mucus.
3. The digestive system uses saliva, enzymes, hydrochloric acid, and mucus to kill bacteria.
4. The circulatory system contains white blood cells that patrol the body and destroy pathogens.
5. Damaged or diseased tissue becomes inflamed, attracting certain white blood cells to light bacteria.
C. Specific immunity-the immune system works against a specific antigen by producing an antibody.
1. In active immunity the body makes its own antibodies in response to an antigen.
a. Some antibodies remain in the bloodstream to tight later infections of the same pathogen.
b. Vaccinationprovides a form of an antigen to provide active immunity.
2. Passive immunity-results when antibodies produced in another animal are introduced into the body
a. Passive immunity does not last as Ion as active immunity.
Does an antibody attached to an antigen make it harmless?
When an antibody attaches onto an antigen it destroys the antigen to help your body fight off a disease.
What is an occasional atypical lymphocytes?
Occasional atypical lymphocytes is found in the bloodstream as an indicator of immune system activation or antigen stimulation in the body. It has more cytoplasm and grows larger in size than normal lymphocytes.
Why does A+ and O+ blood types do not match for blood donating?
People with blood group "O" carries no antigents on their blood cells (in contrary, "A", "B", and "AB" group carries "A","B" and "AB" antigens respectively on their red blood cells). When the "O" group person receives A,B or AB blood type, the body tend to act agains it as they contain A, B or AB antigens and produce their respective antibodies to destroy it (just like treating them like a pathogen!). This causes hemolytic anemia(a condition where red blood cells are destroyed)
Do mice have a stronger immune system than humans?
I believe that mice do have stronger immune systems than humans because of the environment they dwell in.
What does a high neutrophils and a high lymphocytes and high monocytes count mean?
A high neutrophils, lymphocytes, and monocytes count indicates strong towards leukemia, some sort of infection, or disease. Individually they have even more implications.
What would cause fainting with vomiting?
It depends if they really dont feel good or they feel light headed or something like that
What happens with Addison's and chicken pox?
A person that has Addison's disease could become very ill or even die from chicken pox because of their adrenal insufficiency. Getting chicken pox makes the demand for certain hormones to increase which the body cannot do when it has Addison's disease.
How long does it take for the immune system to respond to the disease?
It depends on the person and just how weak the immune system is. Antitoxidants are excellent to boost the immune system. Natural antitoxidants are Pomegranate juice (I drink 1 8 oz glass a day) Cranberries, etc. Go to a health food store and find out more about antitoxidants or go onto the Internet.
How do body's barriers protect the body against pathogens?
The first line of immune defense is the skin and mucus membranes. Skin acts as a physical barrior, blocking pathogens from entering. Mucus wihin the nasal cavity blocks some of the pathogens from entering the body. Cilia also aid in protectiong by acting as a barrior as well. There is also mucus lining the bronchial tubes, which like other mucus, blocks pathogens.
Side effects of natural gas on humans?
METHYL MERCAPTAN is the rotten egg smell added to natural gas to help aid in leak detection. This additive can cause sickness and disturbing symptoms.
If you believe this then you must still believe in witches. I urge readers to see the HBO documentary, 'GASLAND', to discover the frightening truth. This is another example of the government and big business working together with utter disregard for the health and safety of the public.
Where do B lymphocytes develop immunocompetence?
Both type of lymphocytes are made in the bone marrow and only the B - Lymphocytes mature in the bone marrow, whereas the T Lymphocytes travel to the thymus gland where they mature.
What would happen if an individual receives a vaccination containing a weakened pathogen?
Sometimes they will develop mild flu like symptoms and have a low grade fever. With the weakened your body will recognize the pathogen and develop antibodies against it, so your reaction would be milder then contracting the actual illness.
What happens if you have high platelet count?
Having a high platelet count may result to thrombosis, meaning, blood clot formation in the blood vessels. This is quite dangerous since there may be a chance that this blood clot (called thrombus) maybe dislodged (now called, embolus). The embolus (emboli-plural) now circulates in your system and may get stuck in an artery causing obstruction in blood flow. This is dangerous if the emboli obstructs a major artery, depending on the organs involve, it may lead to myocardial infarction (heart attack)congestive heart failure, renal failure, cerebrovascular accident (stroke), etc.
What cells are responsible for synthesis of antibodies?
There are various cells and organs that plays a vital role in the production of antibodies.
Primarily the white blood cells also called as lymphocytes converts to immunoblasts and then convert to plasma cells, from which the antibodies are thus produced.
T-cells and B-cells are antigen specific and produce the antibodies based on the structure and pathogenticity of an antigen. The immune response varies from one antigen to the other.
Do Phagocytic cells ingest pathogens and cellular debris?
The phagocyte that digests cellular debris and pathogens in the human body are called macrophages, or macrophagocytes.
What is the average lifespan of someone with kleinefelters?
5%, only few live from Klinefelter!
Actually the disorder itself doesn't cause death. All it causes is small testicles, possibility of sterile sperm, lean and thin bodies, low muscle tone, and several other symptoms that are not able to be seen. However that does not mean that you can't die from it. Anything is possible with genetics, but the survival right is MUCH higher than 5%.
