Multiple Choice

Which of the following best describes an exocrine gland?

A gland that produces red blood cells

A gland that secretes hormones directly into the bloodstream

A gland that stores and releases neurotransmitters

A gland that releases its products through ducts to an epithelial surface

Verified step by step guidance

Understand the definition of an exocrine gland: Exocrine glands are specialized structures that release their secretions through ducts to an epithelial surface, such as the skin or the lining of the digestive tract.

Differentiate exocrine glands from endocrine glands: Endocrine glands release hormones directly into the bloodstream without using ducts, whereas exocrine glands use ducts to transport their secretions to a specific location.

Identify examples of exocrine glands: Common examples include sweat glands, salivary glands, and sebaceous glands, all of which release their products to external or internal epithelial surfaces.

Eliminate incorrect options: A gland that produces red blood cells is not an exocrine gland; red blood cells are produced in the bone marrow. A gland that secretes hormones directly into the bloodstream is an endocrine gland, not exocrine. A gland that stores and releases neurotransmitters refers to neural structures, not exocrine glands.

Confirm the correct answer: The correct description of an exocrine gland is 'A gland that releases its products through ducts to an epithelial surface.'
