Answer 1

IgA is the main antibody present in saliva, tears, and mucus secretions in connective tissues.

Step-by-step explanation:

IgA is the main antibody present in saliva, tears, and mucus secretions in connective tissues.

Example: IgA plays a crucial role in protecting the mucosa of the gastrointestinal, respiratory, and genitourinary tracts. It coats and protects the extensive mucosal surfaces, preventing the entry of pathogens into the body.

Reference: IgAs populate the saliva, tears, breast milk, and mucus secretions of the gastrointestinal, respiratory, and genitourinary tracts.
