Electrolysis Practice Exam

A gland that delivers its secretions directly into the blood is categorized as?

1. Exocrine gland

2. Endocrine gland

3. Ductless gland

4. Both B and C

The correct answer is: Both B and C

The correct answer is based on the characteristics of endocrine glands. An endocrine gland is specifically defined as a gland that releases its secretions, known as hormones, directly into the bloodstream rather than through ducts. This defining feature allows hormones to travel throughout the body to target organs and tissues, facilitating various physiological processes and regulatory functions. Labeling endocrine glands as "ductless" further emphasizes their unique structure; they do not possess ducts to channel their secretions externally, distinguishing them from exocrine glands, which do release substances through ducts. Therefore, calling an endocrine gland a ductless gland underlines its functional approach to secretion. In summary, the answer highlighting both the endocrine aspect and ductless nature is justified, as both descriptions accurately reflect the gland’s operational role in the body.
