Which organs are considered accessory organs of transmission?

1. Kidneys and Spleen

2. Liver and Gallbladder

3. Heart and Pancreas

4. Lungs and Stomach

The correct answer is: Liver and Gallbladder

The liver and gallbladder are considered accessory organs of transmission, primarily within the context of the digestive system. These organs play crucial roles in processing nutrients and digesting fats. The liver is essential for metabolizing carbohydrates, proteins, and fats. It also produces bile, which is important for fat digestion and absorption in the small intestine. The gallbladder stores and concentrates bile produced by the liver, releasing it into the small intestine when needed to aid in the digestion of dietary fats. Together, these organs ensure that the digestive process runs smoothly and effectively, emphasizing their role in transmission as they assist with the breakdown and absorption of nutrients. In contrast, while other options include organs vital for various bodily functions, they do not specifically relate to the transmission aspect within the digestive system. The kidneys focus on waste excretion and fluid balance, the heart is central to blood circulation and not digestion, and the lungs are involved in respiration. The stomach, although part of the digestive system, is not classified as an accessory organ; it primarily performs the digestion of food rather than facilitating access to nutrients like the liver and gallbladder do.
