Blood serves as the primary transport medium for antibodies, as evidenced by their presence in blood plasma [1] and the circulation of specific types like IgM [2] and IgA [3] within the bloodstream. Furthermore, the blood acts as a site for IgD detection [4] and a restrictive environment for pentameric IgM molecules [5].

claimIgD antibodies are found in the respiratory tract and at low levels in the blood, and may play roles in protecting against respiratory infections and preventing the immune system from attacking the body's own cells and tissues (self-antigens).
claimIgM antibodies circulate in the blood and are among the earliest antibody types to appear during an infection.
claimIgA antibodies are found in the blood, but their primary role is protecting mucosal surfaces, such as the digestive and respiratory tracts.
claimIgM antibodies exist as a pentamer, meaning five IgM molecules travel together, which prevents them from leaving the blood to enter tissues like IgG antibodies.
