Which organ is listed as part of the canine digestive system?

• A. Liver
• B. Heart
• C. Lungs
• D. Spleen

Answer: (A)

The main idea here is understanding which organs contribute directly to digestion in dogs. The liver is an essential digestive organ because it produces bile, a digestive juice that helps emulsify fats and aids in the digestion of fats. It also processes nutrients absorbed from the gut, detoxifies harmful substances, and stores energy as glycogen, supporting overall metabolic processing of what’s ingested. Because of these roles, the liver is part of the digestive system. The other organs listed serve different body systems. The heart pumps blood through the body, the lungs handle gas exchange, and the spleen helps filter blood and support immune function. While these organs are important for overall health, they aren’t components of the digestive tract itself. In dogs, digestion involves the mouth, esophagus, stomach, intestines, and accessory organs like the liver and pancreas, with the liver playing a direct and central role in digestive processes.
