A{'text': 'Release secretions through a duct'}
B{'text': 'Pour secretions directly into blood'}
C{'text': 'Manufacture sweat from blood'}
D{'text': 'Store digestive enzymes in vacuoles'}
Answer & Solution
Correct answer: B. {'text': 'Pour secretions directly into blood'}
1. Glands are classified by how they deliver their secretions. 2. Endocrine glands are **ductless** — they pour hormones **directly into the bloodstream**. 3. Exocrine glands (sweat, salivary) use ducts to reach the surface. 4. Hence the defining feature of endocrine glands is that they are ductless. _Source: Selina Concise ICSE Class 8 Biology Ch 5 "Endocrine System and Adolescence", Key definitions_
