What else can I help you with?
What is it called when the immune response is weaken reduced absent or not functioning properly?
It would be a compromised immune system.
When the immune system becomes terminated or decreased to response?
It can become compromised under immune suppressant drugs therefore will have decreased or no response. It is completely terminated when you die along with everything else.
What occurs during a primary immune response and secondary immune response?
The secondary immune response occurs after an antigen that has already been encountered reappears. For example, if someone had recovered from the flu and later encounters the same strain of that virus, antibodies that were made specifically for that antigen will rise dramatically with almost no lag perod.
Transplanted organs may be rejected in the type of immune response called?
Rejection of transplanted organs occurs in the type of immune response called "graft rejection". This occurs when the recipient's immune system recognizes the transplanted organ as foreign and attacks it, leading to potential organ failure. Medications are often used to suppress this immune response and prevent rejection.
What occurs when the immune system mounts an exaggerated response to a harmless antigen?
hypersensitivity
When an infection occurs number of?
When an infection occurs, the number of pathogens, such as bacteria or viruses, increases in the body. This triggers the immune system to respond, leading to the activation of various immune cells and the production of antibodies. As the immune response escalates, symptoms may manifest, indicating the body's fight against the infection. The outcome depends on the effectiveness of the immune response and the virulence of the pathogens involved.
Which line of immune defense was broken in his immune system when infected?
When an individual is infected, the first line of immune defense, which includes physical barriers like the skin and mucous membranes, is often breached. This allows pathogens to enter the body, where they can interact with the second line of defense, including innate immune responses such as inflammation and phagocytosis. If these defenses are overwhelmed or compromised, the adaptive immune response may also be activated. Thus, the initial breach typically occurs at the level of the physical barriers.
What is the effector response?
Effector response is the phenomenon that occurs after the immune system recognizes a foreign organism. A variety of cells and molecules are then recruited to mount an appropriate response to eliminate or neutralize the organism.
What foreign substance elicits an immune response?
Any sort of "foreign" substance can, and most often will, elicit an immune response under certain curcumstances--provided the immune system is healthy. This would include bacteria, viruses and fungi. Related: An unhealthy, or compromised immune system can act in all sorts of undesirable ways, ranging from low response to threat or injury to actually creating antibodies to attack its own system or other organs and tissue.
Does opportunistic infections occur when immune system is compromised?
Yes
What distinguishes the secondary immune response from the primary immune response?
the secondary immune response is faster and stronger than the first. the primary response also takes a few days to react with the antigen whereas the secondary immune response reacts faster to an antigen.
What is the immune response mediated by naive lymphocytes that occurs on first exposure to antigens?
The pattern recognition receptors check for pathogen patterns, which decides if the innate immune system should be activated.
