Exocrine glands differ from endocrine glands in that exocrine glands secrete fluid into

• A. Bloodstream
• B. Ducts
• C. Lymph
• D. Interstitial space

Answer: (B)

Exocrine glands deliver their secretions through ducts that carry the substance to a surface or body cavity. This duct system is what distinguishes them from endocrine glands, which release hormones directly into the bloodstream to be carried to distant targets. For example, salivary glands pour saliva into ducts in the mouth, and sweat glands release sweat through ducts to the skin surface. The other routes described aren’t how exocrine secretions get out of the gland. Bloodstream is the route for hormones from endocrine glands. Lymph isn’t a typical exit path for glandular secretions, and the secretions of exocrine glands aren’t released into the interstitial space as their endpoint; they travel through ducts to reach their target surfaces.
