Unlike exocrine glands, endocrine glands are characterized by what feature?

Endocrine glands are characterized by being ductless, meaning they release hormones directly into the bloodstream rather than via ducts or tubes. This allows the hormones to travel throughout the body and target various organs and tissues, exerting systemic effects that can regulate processes like metabolism, growth, and mood.

In contrast, exocrine glands have ducts that transport their secretions to specific sites, such as salivary glands and sweat glands. The ability of endocrine glands to function in this manner is crucial for maintaining homeostasis and facilitating communication between different parts of the body through hormonal signaling.
