Document Summary

The head and neck receives the majority of its blood supply through the carotid and vertebral arteries. This article shall explore the anatomy of this arterial system its anatomical course, branches, and clinical correlations. We shall start at the origin of the carotid arteries. The right common carotid artery arises from a bifurcation of the brachiocephalic trunk (the right subclavian artery is the other branch). This bifurcation occurs roughly at the level of the right sternoclavicular joint. The left common carotid artery branches directly from the arch of aorta. The left and right common carotid arteries ascend up the neck, lateral to the trachea and the oesophagus. They do not give o any branches in the neck. At the level of the superior margin of the thyroid cartilage (c4), the carotid arteries split into the external and internal carotid arteries. This bifurcation occurs in an anatomical area known as the carotid triangle.

2. Assume the oxygen capacity of blood is 20ml/100 ml of blood.If the oxygen consumption of the brain is 50 ml/min, the blood is100 % saturated in the carotid arteries carrying blood to the brainand 75% saturated in the jugular veins carrying venous blood fromthe brain, and that brain oxygen consumption is 50 ml/minute:

Calculate the volume of blood flowing through the brain =________ ml/mi
