Final answer:
Exocrine glands are the ones that release their secretions through ducts to the epithelial surface without losing cytoplasm, like the salivary glands.
Step-by-step explanation:
The glands that complete their function without incurring damage to or loss of cytoplasm, such as salivary glands, are known as exocrine glands. These glands release their secretions through ducts that lead to the epithelial surface, in contrast to endocrine glands that secrete directly into the bloodstream. Examples of secretions from exocrine glands include mucous, sweat, saliva, and breast milk, which are all discharged through tubular ducts. The structure of exocrine glands can be either unicellular, like goblet cells, or multicellular.
