Why is clear embalming fluid often purged from the nose and mouth during the preparation of cases who died of pulmonary tuberculosis?

The correct answer highlights that the lung capillaries are damaged by the disease. In cases of pulmonary tuberculosis, the lungs may be severely affected, leading to complications such as hemorrhaging or the presence of excess fluids. As a result, embalming fluids may find their way into the lung capillaries, and purging these fluids from the nose and mouth actually helps in preventing leakage of the embalming fluid that could occur due to the compromised state of these capillaries.

This purging process is important because it assists in maintaining the overall appearance and integrity of the body during and after the embalming process, ensuring that the effects of the disease do not lead to further complications in preparation for viewing.

Understanding the nuances of how certain diseases like tuberculosis affect the body and its vascular systems is critical for funeral service professionals, as it impacts their approach to embalming and preparation. This knowledge ensures they are equipped to handle such cases sensitively and effectively.
