Why do white blood cells attack your internal organs?
In a healthy person, white blood cells only attack invading germs, and would not attack the person's own internal organs. However, there are autoimmune diseases, which cause the immune system to become confused and to attack the wrong targets.
Which is the first part of the immune system to attack an invader?
Lysozymes
Is dog to human testicle transplant possible?
No. Your immune system would attack the foreign organ.
What would happen if your immune system stopped working?
Germs would attack you body and you would get sick easily and more often.
Will a puntured testicle heal?
It will heal, but there is a chance that it could lead to sterility. The testicle is an immunoprotected site. This means that normally your immune system can't get in there. This is important because your sperm only has half of your genetic material, and if your immune system were to see them, it would attack them. Any time a testicle is punctured, it has a chance of allowing the immune system the ability to attack the sperm.
What is the body's defense system?
It would be their immune system.
How would HIV kill you?
The HIV virus attacks the Immune system, disabeling its defenses and leaving you open to attack from other viruses.
Which system protects the body from pathogens?
If a pathogen enters the human body certain types of white blood cells send antibodies to attack the pathogen, which stops it from pruducing toxins and stops it from re-infecting the body. the second type of white blood cell would attack the pathogen and slowly engulf it, absorbing and destroying it. i love science :)
What is the effect on blood pressure to an attack by a mugger?
Blood pressure would increase due to sympathetic nervous system stimulation.
What system does the spleen belong?
The spleen would be in the immune system. It's considered to be a large lymph node, removing old red blood cells.
Why is Type O negative a potential universal donor in an emergency?
Red Blood Cells have specific antigenic markers on their surface. There are two types of protein A and B. If you are type A blood your RBCs have protein A, if you are type B you have B proteins, if you are AB you have both and if you are O you have neither. These proteins are detected by the bodies immune system, which detect the protein specific to you and as a result do not attack that cell. If you were Group A and were to receive Group B blood, your immune system would attack all the B blood - making it pointless and often dangerous to give it. Blood type O - often called the universal donor - has no antigenic marking proteins and therefore will not be broken down by the recipients immune system.
Do you need an immune system?
You do need a immune system because you would be sick and die
