The German cockroach will eat almost anything, but is particularly attracted to fermented foods and beverage residues (beer spills). If water is present, adults can live about a month without food, but young nymphs will die of starvation within 10 days. Without food or water, the adults die in less than two weeks.
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.
It supplies blood to all parts of the body with the exception of the lungs. The aorta ascends from the heart and forms an arch, from which arise two subclavian arteries. Each subclavian has two main branches, the common carotid and the vertebral. Both of these carry blood to the brain. Each common carotid divides into an external carotid artery, which supplies blood to the face and an internal carotid artery which supplies the brain with blood.
