Question

Difference between endocrine and exocrine glands is that

• A. endocrine glands release hormones, exocrine glands release waste
• B. endocrine glands are ductless, exocrine glands release secretions into ducts
• C. endocrine glands release their secretion in large amount, exocrine gland release their secretion is trace amounts
• D. none of the above

Answer 1

The correct option is B endocrine glands are ductless, exocrine glands release secretions into ducts

Glands that secrete enzymes are called exocrine glands. Whereas those glands that secrete hormones are called endocrine glands. The hormones are released directly into the blood in trace amounts. Whereas enzymes are secreted into the ducts. The quantity of enzymes secreted is large when compared to the amount of hormones that are secreted. Since the endocrine glands do not involve any ducts, they are also known as ductless glands.
