The acquired immune response is also known as the specific immune response. This involves the presentation of micro organisms antigens by macrophages to T and B lymphocytes (T and B cells). T cells and B cells specific to these antigens will then go through clonal expansion (mass production) to help carry out a specific response that has been 'acquired' as a direct result or particular microorganisms antigens.
T cells are divided into T helper and T killer, and B cells into memory cells and plasma cells.
T helper cells aid B cells in their production and carrying out their functions. T killer cells kill infected cells (those containing viruses or bacteria, as detected by their presentation of antigen on MHC Class 1 receptor molecules on their surface).
B cells differentiate into plasma cells and memory cells, plasma cells produce antibodies specific to the type or types of antigens detected. Memory cells have the ability to live for long amounts of time and quickly differentiate into plasma cells should the same antigens present at a later date, allowing a faster and more efficient immune response if infected again with the same microorganism.
The acquired immune response usually takes 7-10 days after initial presentation of the antigens by macrophages - unless this is a secondary response, in which case the person should have already produced memory cells so can deal with the invading microorganisms faster and more efficiently.
The innate (passive) immune system is responsible for initial responses, this is non specific and involves neutrophils largely.

What is the difference between the innate immune response and the acquired immune response?
The innate immune response is the body's first line of defense against pathogens and is non-specific, meaning it does not target specific pathogens. It includes physical barriers like skin and mucous membranes, as well as immune cells like macrophages and natural killer cells. The acquired immune response is more specialized and involves the activation of immune cells such as T and B lymphocytes that target specific pathogens based on memory from past exposures.
Explain the difference between innate response and an acquired response?
The innate immune response is the body's immediate, non-specific defense mechanism against infections. It is always ready to respond to invaders. The acquired immune response is specific to a particular pathogen and involves the production of antibodies and memory cells for long-term protection. It takes time to develop but provides a targeted defense against specific pathogens.
Two blood cells chiefly responsible for the acquired immune response?
Lymphocytes
This is the first word in the acronym AIDS?
"AIDS" is the acronym for "Acquired Immune Deficiency Syndrome".
What are two ways in which active immunity can be acquired?
Active immunity can be acquired through natural exposure to an infectious agent, which triggers the body's immune response to produce antibodies. It can also be acquired through vaccination, where the immune system is exposed to a weakened or inactivated form of the pathogen, leading to the production of antibodies without causing illness.
When was Journal of Acquired Immune Deficiency Syndromes created?
Journal of Acquired Immune Deficiency Syndromes was created in 1988.
What is aids the acronym for?
AIDs - Acquired Immune Deficiency Syndrome
What are AID's?
Acquired immune deficiency syndrome or acquired immunodeficiency syndrome.
Type of resistance that is acquired as a result of developing a disease?
Acquired resistance from developing a disease is known as active immunity. This occurs when the body's immune system recognizes a pathogen during infection and generates a specific response to combat it. The immune memory developed during this process helps protect against future encounters with the same pathogen.
What is Acquired Immune Deficiensy Syndrome caused by?
Acquired Immune Deficiency Syndrome (AIDS) is caused by the Human Immunodeficiency Virus (HIV).
Which part of a specifics immune response?
Looking for antigens is part of a specific immune response.
What white blood cell types are involved in the second line of defence?
The immune system's third line of defense is called specific resistance or acquired immunity. The system depends on antigens which are mostly proteins which function as a producer of the immune response.
