Saliva, tear, milk, etc are exocrine secretions and immunoglobulin molecules are present in such secretions.
In saliva, both Ig A and Ig G are present. Ig G generally reaches saliva from serum, but Ig A is locally produced by plasma cells present in salivary glands.
In milk, at least four types of immunoglobulins are detected, but Ig A is the most abundant type.
