Immune System
This category is for questions about how our bodies identify and fight off disease, infection or pathogens through specialized cells, tissues and organs. The system that does this is called the immune system. It produces antibodies which recognize intruders and neutralizes potentially pathogenic organisms or substances.

A substance prepared from killed or weekend pathogens?
it is called Vaccine whcih when administrated in any individual provide immunity against that pathogen..
Do pathogenic bacteria thrive in distilled water?
No. Like all living things, bacteria need nutrients to support their vital functions. Without a source of nutrients the bacteria will die. Distilled water is pure water with no dissolved salts, proteins or carbohydrates.
Which country has the most unhealthiest people?
Sierra Leone, according to the World Health Organization.
How does cellular immunity protect the body?
Cytoxic T-Cells differentiate and produce identical clones. They travel to the infection site and release enzymes directly into the pathogens, causing them to lyse and die.
When an antigen binds to a Class 1 MHC molecule it stimulates what cell?
Class I MHC molecules present antigens to cytotoxic T-cells (which are CD3+CD8+).

Should you get a tattoo if you have strep?
Certainly not, I have many tattoo's, one of which became extremely infected because I had strep. The open wound was attacked by my immune system and it was not able to heal properly. The bacteria grew so quickly, that within a 72 hour span, my tattoo no longer had a shape to it, it was literally a BLOB of pus and plasma. ( I then had to go to the hospital every day for dressing to be put on my arm and I had to take antibiotics for 2 weeks to kill anything that may have grown there.)
( Also, be aware that I DID contact my tattoo artist the moment it felt hot and when I began feeling feverish symptoms, including migrane with aura. I followed cleaning instructions and care, it was seemingly a normal reaction, but it turned awful, quickly.)
I advise that until you are in optimal shape and health to avoid getting any tattoo, otherwise your body will go into overdrive, possibly causing severe infection and of course fever.
The tattoo that became infected now exists however has lost a lot of its luster, there is plenty of scaring around the areas that could not be helped immediately and the color has faded substantially.
Of course, this is not an attempt to fear monger, tattoo's are risky business, so take care, and happy + safe tattooing! :)
Of the 2 branches of the immune system which system begins to respond immediately?
The innate immune system is the branch of the immune system that responds immediately to pathogens. It provides rapid but non-specific defense mechanisms, such as physical barriers and inflammatory responses, against a wide range of invaders.
What kind of infections do people with compromised immune systems get?
People with comprimised immune systems are susceptible to all the infections commonly found in the population. They are also able to develop "opportunistic infections."
There are a variety of opportunistic infections. A few include thrush, kaposi's sarcoma, pneumocystis pneumonia and cytomegalovirus.
What is the ''Immune system'' for?
The immune system is very important to overall health. It is the system in our body that protects from disease and illness. It is important to keep it operating at peak levels in order to live a healthy lifestyle. In order to do this you must eat a healthy and nutritious diet or supplement with the right vitamins and minerals.
What is the difference between T cell receptors and MHC molecules?
T cell receptors bind to MHC class 1 molecules. MHC class 1 molecules bind to peptides (self or foreign) and present it to the cell's membrane. The job of a T cell is to decide what is presented on the MHC class 1 cell whether to leave it alone or to activate to destroy it because it is non-self.
Could it just be a sore muscle instead of my appendix?
See a doctor, appendix problems start in the middle of your tummy and move to the right hand side. It can be fatal if it bursts. Muscle pain will subside, appendix pain will not.
An antibody oponizes invading organisms is in order to enhance the function of?
To enhance the function of phagocytosis. The antibody binds to the antigen (on the organism). The antibody also binds to the phagocyte thus facilitating the coming together of the antibody and phagocyte and phagocytosis can then proceed.
When does lens convexity increase?
when the degree of convergence of a convex lens placed in air increases, we say its convexity has increased. as the power of a lens is the measure of degree of its convergence or divergence, we can increase the convexity of a lens increasing its power
this is further achieved by decreasing its focal length.
as focal length is inversly proportional to the refractive index of lens we have to decrease in order to increase its convexity.
