Practice questions
Q1Which of the following antibodies is found in greater quantity in mother's milk?
Explanation
IgA, especially secretory IgA, is the major antibody present in breast milk. It helps protect the infant's mucosal surfaces, particularly in the gut and respiratory tract, without producing a strong inflammatory reaction. IgD is mainly found on the surface of certain B cells and is not abundant in milk. IgG is important in blood and can cross the placenta before birth, but it is not the main milk antibody. IgM participates in early immune responses, yet it is present in lower amounts than secretory IgA in mother's milk.
