Does The Body Have A Defense Mechanism Against Wounds
In freudian psychoanalytic theory, defence mechanisms (or defense mechanisms) are psychological strategies brought into play by the unconscious mind to manipulate, deny, or distort reality (through processes including, but not limited to, repression, identification, or rationalization), and to maintain a socially ...Read more
Does the eye, if exposed to viruses/bacteria/cancer fluids, have any protective mechanisms? Like the way one's immune system attacks viruses in blood?
Broad question: The immune system tailors it's response to various viruses and to various bacteria in several different ways that can be quite complex depending on how far you want to drill down. Some viruses are destroyed by specialized cytotoxic cells that kill the infected host cell thereby reducing viral replication. Some bacteria are lysed by a combination of antibodies and other blood components. ...Read more
Does HIV evading the immune system support the idea of an evolutionary race between pathogens and hosts?
Is it true that in certain diseases, the immune system attacks your body - it causes your immune system to produce antibodies against your own tissues?
Yes: Body can make antibodies as well as cells that damage or destroy its own cells and tissues and are the basis for some diseases, e.g., systemic lupus, hemolytic anemia, myasthenia gravis, multiple sclerosis, rheumatoid arthritis and more. See this site for more info. http://www.ncbi.nlm.nih.gov/pubmedhealth/pmh0001819/. ...Read more
Our body has strong immune system to fight with a number of foreign pathogen to prevent illness or desease. So why is it that we still become ill?
During rheumatic fever, when heart is affected, since it has lesser ability to pump blood to body, won't it weaken the immune and defense system?
What could the immune system produce that attaches itself to a pathogen and marks the pathogen for death?
Few dif. things: Antibodies are proteins made by certain immune cells that seek out and bind to pathogens. Once bound, antibodies can activate other proteins in your blood called complement, which can poke holes in the bug and kill it. Sometimes, complement can bind to the bug on its own. If the bug survives that, both antibody and complement can act as handholds for immune cells to grab onto the bug and eat it. ...Read more
What elements of the immune system would help rid the body of a virus that had already invaded a cell?t
Yes: Not possible but almost a universal occurrence. ...Read more
Yes: If viral antigens or epitopes are expressed on the surface of the infected cell, then yes. They may "fix complement" leading to lysis. ...Read more
Diarrhea: good & bad: In some ways, 'yes' diarrhea can be good -since the body is dumping out the toxin, germ or whatever caused the diarrhea. On the other hand, some germs cause excessive diarrhea to increase their spread -think of the mess if you don't have proper toilets and lived in a cave. The other downside to diarrhea is loss of salts (electrolytes) and water -which can be quite dangerous depending how severe. ...Read more

What is the point of the human body getting a fever when you have a cold? Is the fevers purpose to kill off the germs?
Fever: Great question. There is substantial evidence to suggest that some infections in which fever occurs are limited because the causative organisms do not tolerate the increase in temperature well. Fever is very non-specific and is simply a response to cytokines released by cells responding to inflammation, or an imbalance of temperature generation with inadequate loss of temp thru sweating, etc. ...Read more
Does seawater promote the healing of surface wounds and infections? If so, what are the likely causal mechanisms at play?
No, no, no.: I've been hearing this for 30 years; swim in the ocean, your rash, wound, or whatever will heal. This is further evidence that your parents are not doctors. Seawater contains nasty bacteria, particularly in estuaries and near rocks or coral, and in areas close to fisheries, mines, farms, stormwater drains and sewage plants. People have died. If you have a skin wound or rash, stay out of the ocean! ...Read moreSee 1 more doctor answer
Skin Protection: Skin protects the human body from many external forces. It is the body's initial guard against bacteria and other agents of infection (toxins, harmful liquids and gases), most of which are unable to penetrate the dense design of the skin and infiltrate the organs below; they're caught on its surface. Skin protects the body from exposure to ultraviolet light. ...Read more
If infectious bacteria overpowers the immune system, how does All bacteria that is killed or die still get cleared by white blood cell and the body?
Clear dead bacteria: 22 M asks: If infectious bacteria overpowers the immune system, how does All bacteria that is killed or die still get cleared by white blood cell and the body? ANS: The WBCS engulf them and bacteria die. They spit the digested parts/chemicals back into the blood. And they are cleared or reused by liver and kidneys. ...Read more
