Does the body have a defense mechanism against wounds?

Does the body have a defense mechanism against wounds?

An amazing system: As dr. Berg said, our body's defense mechanism against wounds is amazing. It is truly extraordinary and exceptionally effective. If we didn't have such an effective system, wounds would never heal and everyone would die from infection. ...Read more

Defense Mechanism (Definition)

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?

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?

Yes: Tear has enzymes and antibody (iga class primarily) .Lysozymes etc to act against invaders. The constant flushing from tear flow also helps cleanse the eye surface. ...Read more

How does the immune system work when it encounters a type of virus/bacteria?

How does the immune system work when it encounters a type of virus/bacteria?

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?

Does HIV evading the immune system support the idea of an evolutionary race between pathogens and hosts?

Constant: Bacteria , viruses, and we are all constantly evolving to adapt to the environment likely through epigenetic actions on the genes. Thus HIV virus is not exception. ...Read more

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?

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?

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?

Immune reaction: Part of getting ill is that viruses like influenza constantly mutate and evolve to get around the immune system. The other part of feeling ill is a consequence of reactions caused by the immune system while actually fighting infections! ...Read more

What could the immune system produce that attaches itself to a pathogen and marks the pathogen for death?

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

What  elements of the immune system would help rid the body of a virus that had already invaded a cell?t

T cell: T cells - cytotoxic t-cell mediated immunity againt virus infected cells through both direct and indirect killing mechanisms. ADCC - antibody mediated cytotoxicity: antibody also play a role in bringing T cells to the virus-infected cells. ...Read more

Does the human body even use the complement system at all to fight-off viruses?

Does the human body even use the complement system at all to fight-off viruses?

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

Does diarrhea/loose stool serve a purpose, like ridding the body of an invader more quickly?

Does diarrhea/loose stool serve a purpose, like ridding the body of an invader more quickly?

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?

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?

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 more

How does the skin protect the body against bacterial growth?

How does the skin protect the body against bacterial growth?

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?

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

Isit 100% that someone that has HPV 6.11, 16, 18 and it will cause cervical cancer or immunue system can fight it of the body if its strong?

No: There are very few things that are 100%. While these serotypes are proven to be the most virulent forms of hpv associated with cancer, even this does not guarantee a future of malignancy. ...Read more

Is a fever a defense mechanism for the human body. What will happen if a fever is allowed to run high?
