The German cockroach will eat almost anything, but is particularly attracted to fermented foods and beverage residues (beer spills).

The common carotid arteries split into two main branches â the internal carotid artery and the external carotid artery. The external carotid artery is the only division of the common carotid that gives branches to the neck region and supplies the external structures of the head and face.
The common carotid artery is the artery that supplies blood to the head and neck. In the mid-neck, it divides into external and internal carotid arteries. The external carotid artery supplies blood to the face and scalp, whereas the internal carotid artery supplies blood to the brain.
