Final answer:
The liver dispenses wastes into the bile duct and gallbladder by producing bile.
Step-by-step explanation:
The liver dispenses wastes into the bile duct and gallbladder. It produces bile, which is then secreted into the duodenum. Bile breaks up large globules of lipids into smaller globules, making it easier for enzymes to break them down. The gallbladder stores and concentrates bile before secreting it into the small intestine.
