Which is a common embalming technique?

Injecting embalming fluid through the carotid artery is a standard method utilized in the embalming process. This technique allows for the efficient distribution of embalming chemicals throughout the body, facilitating preservation and delaying decomposition. The carotid artery is chosen because of its significant size and its extensive branching system that ensures the fluid reaches various tissues and organs. This method is critical for effective embalming, as it helps maintain the body in a presentable condition for viewing during funeral services.

Other methods listed, such as heating the body with infrared light, freezing, or using dry ice, are not typical embalming practices. These alternatives may be utilized in different contexts, such as in certain types of preservation for medical or scientific purposes, but they do not align with the conventional techniques used in preparing a body for funeral services.
