Discuss why endocrine glands are called ductless glands?

Explanation

**Step-by-Step Solution:**

1. **Definition of Endocrine Glands**: Endocrine glands are specialized glands in the body that produce and secrete hormones directly into the bloodstream.

2. **Understanding the Term "Ductless"**: The term "ductless" refers to the absence of ducts or tubes that transport the secretions. Unlike exocrine glands, which have ducts to carry their secretions to specific sites (like sweat glands or salivary glands), endocrine glands lack these structures.

3. **Hormone Secretion**: Endocrine glands secrete hormones directly into the blood. This means that once hormones are produced, they are released straight into the circulatory system, allowing them to travel throughout the body and reach their target organs or tissues.
