How many liters of fluid can the average adult hold in their abdomen?

An average adult can typically hold up to around 3 to 5 liters of fluid in the abdominal cavity, depending on factors such as body size and the presence of certain medical conditions. The correct understanding is that while the absolute capacity can vary, the upper limit is generally recognized to be close to 5 liters.

While 10 liters exceeds the anatomical capacity of the human abdomen and is beyond medically viable conditions, other values like 3 liters and 7 liters fall within the reasonable upper limits that can be experienced temporarily due to conditions such as ascites, where fluid accumulates due to liver disease or other pathological states. However, in the context of normal or maximum conditions, 5 liters is consistent with medical knowledge, making it a more accurate estimate compared to the other options provided.
