Verified step by step guidance

Understand the basic function of glands: Glands are specialized organs that produce and release substances such as hormones or enzymes.

Differentiate between endocrine and exocrine glands: Endocrine glands release hormones directly into the bloodstream, while exocrine glands release their secretions through ducts to the outside of the body or onto a surface within the body.

Identify the role of ducts: Endocrine glands do not have ducts, as their hormones are secreted directly into the bloodstream. In contrast, exocrine glands have ducts that transport their secretions to specific locations.

Clarify the secretion targets: Endocrine glands target distant organs and tissues through the circulatory system, whereas exocrine glands target specific areas, such as the skin or the digestive tract, through their ducts.

Review the options given: The correct statement is that endocrine glands secrete hormones directly into the bloodstream, which distinguishes them from exocrine glands that use ducts for secretion.
