Which artery is typically injected first during the embalming process?

The right common carotid artery is typically injected first during the embalming process for several important reasons. This artery is usually more accessible and provides direct access to the head and neck region, where blood circulation is crucial for effective embalming. By starting with the right common carotid artery, embalmers can ensure that the embalming fluid reaches the major areas of the body, especially the face, which is a focal point for viewing during final arrangements.

Additionally, the right common carotid artery is generally larger and preferred for initial fluid injection because it can facilitate a higher flow rate of embalming fluid. This is particularly significant in achieving thorough distribution throughout the vascular system, allowing for better preservation and disinfection of tissues.

In contrast, although the left common carotid artery could also be used, it is less commonly chosen first due to its anatomical position and potential complications that may arise from other structures nearby. The other arteries - the femoral artery and the brachial artery - are typically used for injection in specific circumstances but are not standard for the initial injection due to their locations and the areas they serve.
