Which organs are vulnerable to direct interior attack from exogenous pathogenic factors?

The organs most vulnerable to direct interior attack from exogenous pathogenic factors are the Large Intestine, Stomach, and Uterus. This is because these organs are more directly exposed to external pathogens due to their functions related to digestion, absorption, and elimination.

The Large Intestine and Stomach are involved in processing food and waste, which means they are frequently interacting with external substances that can carry pathogens. This makes them susceptible to interior attacks from exogenous factors, such as microorganisms or toxins introduced through food and drink.

The Uterus is also considered vulnerable as it can be affected by exogenous factors, particularly in cases of gynecological infections or conditions influenced by external pathogens. The entry points for exogenous factors can have a direct impact on the functional integrity of these organs since they can be sites of inflammatory responses or infections.

This understanding emphasizes the significance of protective measures and treatment approaches in Chinese medicine that focus on reinforcing the body's defenses against such invasions, particularly in these vulnerable organs.
