What are the three phases of immune response?
The cellular immune response consists of three phases: cognitive, activation, and effector..
How long does an immune response take?
The adaptive, or acquired, immune response takes days or even weeks to become established—much longer than the innate response; however, adaptive immunity is more specific to pathogens and has memory. Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination.
How does immune system response to virus?
A virus-bound antibody binds to receptors, called Fc receptors, on the surface of phagocytic cells and triggers a mechanism known as phagocytosis, by which the cell engulfs and destroys the virus. Finally, antibodies can also activate the complement system, which opsonises and promotes phagocytosis of viruses.
What are signs of a weak immune system?

What are the 4 phases of the immune response?
This can be broken down into four stages: the lag, exponential, steady state, and declining phases. This is the time from initial antigen exposure to when antibodies are detected in the blood, and takes about a week. In this time, specialized B and T cells are activated by contact with the antigen.
What are the signs of immune response?
SymptomsFrequent and recurrent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections.Inflammation and infection of internal organs.Blood disorders, such as low platelet counts or anemia.Digestive problems, such as cramping, loss of appetite, nausea and diarrhea.Delayed growth and development.More items…•
What are the 2 types of immune response?
Although all components of the immune system interact with each other, it is typical to consider two broad categories of immune responses: the innate immune system and the adaptive immune system. Innate immune responses are those that rely on cells that require no additional “training” to do their jobs.
What is the first immune response?
Conclusion. Innate immunity is the first immunological, non-specific mechanism for fighting against infections. This immune response is rapid, occurring minutes or hours after aggression and is mediated by numerous cells including phagocytes, mast cells, basophils and eosinophils, as well as the complement system.
At what age is your immune system the strongest?
When your child reaches the age of 7 or 8, most of his immune system development is complete.
What is meant by the immune response of the body?
The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful.
