Glandular secretions are substances produced and released by glands in the body. These secretions can include hormones, enzymes, and other fluids that play essential roles in various physiological processes. For example, the endocrine glands release hormones directly into the bloodstream, regulating functions like growth and metabolism. In contrast, exocrine glands secrete substances through ducts to specific locations, such as saliva from the salivary glands or digestive enzymes from the pancreas. Both types of glandular secretions are crucial for maintaining homeostasis and supporting overall health in the body.
