Which type of glands are classified as ductless?

Endocrine glands are classified as ductless glands because they release their hormones directly into the bloodstream rather than through ducts. This direct secretion allows for the rapid distribution of hormones throughout the body, enabling them to regulate various physiological processes such as metabolism, growth, and mood.

In contrast, exocrine glands, such as salivary and sweat glands, have ducts that transport their secretions to specific sites, like the oral cavity or surface of the skin. Thus, while both types of glands play essential roles in the body’s functions, only endocrine glands operate without the use of ducts, reflecting their unique method of hormone distribution.
