The carotid arteries are very similar in pigs and humans. The cardiovascular system is conserved across all mammal species including pigs and humans.
In humans, there are no bicarotid trunks like there are in cats. Both animals do receive oxygen rich blood from these arteries.
In the human, the right common carotid artery branches from the brachiocephalic artery, whereas the left common carotid artery comes directly from the aortic arch. In the cat, both common carotid arteries branch from the brachiocephalic artery.

Carotid arteries supply blood to brain . Blood is supplied to the entire brain by 2 pairs of arteries: the internal carotid arteries and vertebral arteries. The right and left vertebral arteries come together at the base of the brain to form a single basilar artery. The basilar artery joins the blood supply of the internal carotid arteries in a ring at the base of the brain. This ring of arteries is called the circle of Willis. The circle of Willis provides a safety mechanism...if one of the arteries gets blocked, the "circle" will still provide the brain with blood.
The left and right common carotid arteries branch off the arch of the aorta. They travel up through the neck and at the level of C4 divide into external and internal carotid arteries. The internal travels more deeply and ultimately the blood it carries supplies areas of the brain, the external is more superficial and is largely responsible for supplying areas of the neck and face.

Brachiocephalic Artery
The common carotid artery belongs to the circulatory system, specifically the arterial system. It is responsible for supplying oxygenated blood to the head and neck. The common carotid artery bifurcates into the internal and external carotid arteries, which further supply blood to the brain and face, respectively.
The division of the brachiocephalic trunk is formed by the right subclavian and the right common carotid arteries.
The carotid arteries bring oxygenated blood to the neck, face, head and brain.The arteries that carry flood to the structures of the head are the carotid arteries. The common carotid arteries split to form the internal and external carotid artery. The external carotid supplies blood to most of the facial and scalp structures, while the internal carotid enters the skull and supplies blood to the brain via the middle cerebral arteries.
