What is the main function of exocrine glands?

Ensure hormone regulation in the bloodstream
Release their secretions through ducts to specific organs
Provide support and structure to tissues
Facilitate nerve signal transmission

The correct answer is: Release their secretions through ducts to specific organs

The main function of exocrine glands is to release their secretions through ducts to specific organs. Exocrine glands secrete substances such as enzymes, mucus, sweat, and saliva directly to the site of action through these ducts, unlike endocrine glands, which release hormones directly into the bloodstream. This mechanism allows exocrine glands to play critical roles in processes such as digestion (e.g., the pancreas secreting digestive enzymes), thermoregulation (sweat glands), and lubrication (salivary glands). By having a dedicated pathway through which their products are delivered, exocrine glands can ensure that their secretions are efficiently distributed to the target tissues where they are needed, making them integral to various physiological functions in the body.
