How is blood typically removed during the embalming process?

Blood is typically removed during the embalming process through the method of arterial injection and venous drainage. This technique involves inserting an embalming fluid into the arterial system, which simultaneously pushes the blood out of the body through the veins. This method is effective because it allows the embalmer to replace the blood with preservative chemicals systematically, ensuring that the body is properly embalmed and that the natural coloration and appearance are maintained.

The approach of arterial injection allows for a thorough distribution of embalming fluid, while venous drainage ensures that the blood is effectively removed, creating a suitable environment for preservation. This method is standard practice in embalming, as it adheres to the principles of fluid dynamics and ensures the best results for the embalming process.

Other options such as suctioning from the mouth, using a vacuum pump directly, or making incisions in the thoracic cavity are not part of the traditional embalming process and do not provide the thorough and systemic removal of blood needed for effective embalming.
