What are two immunoglobulins that are found in the secretions of exocrine glands?

Answer 1

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.
