IMMUNOLOGY

Detailed explanation-1: -Without B-cells, your body would not be as effective at fighting off a number of common bacteria and viruses; and you would lack the long-lasting “memory antibody” function that is typical after recovering from an infection or after being immunized against a specific infectious invader.

Detailed explanation-2: -You might go from one illness to another, without ever recovering in between. When the failure is severe, you will see more complications from those illnesses and infections, and you’ll recover much more slowly. Instead of bouncing back within days or a week, you could suffer for several weeks or months.

Detailed explanation-3: -Adaptive immune responses depend on the ability to recognize and eliminate recurrent pathogens, resulting in the generation of memory lymphocytes. The capacity of memory T cells to rapidly mobilize and initiate a potent recall response enhances protective immunity against previously encountered pathogens.

Detailed explanation-4: -What can go wrong with the immune system? Sometimes a person may have an immune response even though there is no real threat. This can lead to problems such as allergies, asthma, and autoimmune diseases. If you have an autoimmune disease, your immune system attacks healthy cells in your body by mistake.
