Question

Quizplus · Accepted Answer

Exocrine secretions are released onto an epithelial surface. Exocrine glands secrete their substances through ducts onto epithelial surfaces, such as sweat glands, salivary glands, and digestive glands. The other options are incorrect as nuclear and microtubular secretions are not types of glandular secretions, and hormonal and endocrine secretions are released into the bloodstream rather than onto epithelial surfaces.
