What is the primary difference between an endocrine gland and an exocrine gland?

Endocrine glands release enzymes into the digestive tract, while exocrine glands secrete hormones into the bloodstream.

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands release their secretions through ducts.

Endocrine glands function only during puberty, while exocrine glands are active throughout life.

Endocrine glands are only found in the brain, whereas exocrine glands are located throughout the body.

Verified step by step guidance

Understand the basic definitions: Endocrine glands are glands that secrete hormones directly into the bloodstream. Exocrine glands, on the other hand, release their secretions through ducts to the outside of the body or onto a surface within the body.

Identify the function of endocrine glands: They produce hormones that regulate various bodily functions such as metabolism, growth, and mood. These hormones are released into the bloodstream and transported to target organs or tissues.

Identify the function of exocrine glands: They produce substances such as enzymes, sweat, or saliva, which are released through ducts to specific locations, such as the digestive tract or skin surface.

Clarify the misconception: Endocrine glands do not release enzymes into the digestive tract; that is a function of certain exocrine glands. Similarly, exocrine glands do not secrete hormones into the bloodstream.

Summarize the primary difference: Endocrine glands secrete hormones directly into the bloodstream without using ducts, while exocrine glands use ducts to release their secretions to specific locations.
