Visceral organ exhibiting both exocrine and endocrine functional properties:
Show answer Hide answer
Answer: B. Pancreas
Explanation
The pancreas acts as a dual gland producing both exocrine digestive juices and endocrine hormones. Exocrine secretions travel through ducts into the small intestine to break down food molecules. Endocrine secretions enter the bloodstream directly to regulate systemic metabolic processes. Glands in the human body are classified primarily as either exocrine with ducts or endocrine ductless. The pancreas performs both roles simultaneously to support digestion and blood sugar homeostasis. Acinar cells produce enzymes while islet cells produce hormones within the same organ structure.
Pancreatic disorders disrupt both digestive enzyme release and blood glucose regulation simultaneously. Medical treatments for pancreatic failure must address both exocrine and endocrine deficiencies. This unique physiological dual role makes the pancreas vital for human survival and metabolism. The heart functions exclusively as a muscular pump to circulate blood without exocrine duties. The stomach is primarily an exocrine digestive organ lacking significant endocrine hormone output. The liver has metabolic and exocrine roles involving bile, but it is distinct from the pancreas.
