Humoral Immunity Quiz

What type of immunity is humoral immunity?

What does humoral immunity primarily protect against?

Which antibody is the first to be presented when exposed to infection for the first time?

During the primary immune response, how long is the lag period before antibodies are detectable in the serum?

What is the secondary response in immunity?

What antibody declines earlier than IgG?

Which antibody follows IgM when exposed to infection for the first time?

What is humoral immunity primarily directed against?

How long does it take for the serum antibody concentration to decline after reaching its peak during an immune response?

Humoral immunity is a component of the adaptive immune system that involves the production of antibodies by B cells.
It primarily protects against extracellular pathogens, including bacteria and viruses found in body fluids.

The first antibody to be produced during a primary infection is Immunoglobulin M (IgM).
In the primary immune response, there is a lag period of about 4 to 7 days before antibodies become detectable in the serum.

The secondary immune response occurs upon re-exposure to the same pathogen, resulting in a faster and more robust antibody production.
Immunoglobulin G (IgG) follows IgM in the immune response, providing long-term protection.

Immunoglobulin M (IgM) levels typically decline faster than IgG levels after an immune response peaks.
Serum antibody concentration will begin to decline after reaching its peak, notably over several weeks to months, depending on the immune response.
