Verified step by step guidance

Understand that immunoglobulins, also known as antibodies, are proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.

Recognize that there are five main classes of immunoglobulins in humans, each with distinct roles and properties: IgA, IgD, IgE, IgG, and IgM.

IgA is primarily found in mucous membranes, such as the respiratory and gastrointestinal tracts, and plays a crucial role in mucosal immunity.

IgD is present in small amounts in the blood and is involved in the activation and regulation of B cells.

IgE is associated with allergic reactions and is found in the lungs, skin, and mucous membranes, while IgG is the most abundant antibody in the blood and is essential for fighting bacterial and viral infections. IgM is the first antibody produced in response to an infection and is primarily found in the blood and lymphatic fluid.
